Birth Name: Miranda Taylor Cosgrove

Place of Birth: Los Angeles, California, United States

Date of Birth: May 14, 1993

Ethnicity: Irish, English, French, one eighth Mexican, some degree of German [including Alsatian], distant Welsh, possibly other

Miranda Cosgrove is an American actress, singer, songwriter, and host. Her roles include the series Drake & Josh and iCarly, the films School of Rock, Yours, Mine & Ours, Keeping Up with the Steins, The Wild Stallion, The Intruders (2015), 3022, North Hollywood, and, in voice role, Khan Kluay, the Despicable Me franchise, and A Mouse Tale; and as the host of Mission Unstoppable with Miranda Cosgrove. She is also known for her song “Kissin U.”

On her Twitter account, she stated:

I’m Irish, English, and French. People always think I’m a lot of different nationalities though which I think is pretty cool :)

Oddly, Miranda did not mention her one eighth Mexican ancestry. Miranda’s maternal grandfather’s mother, Mary Castimello/Costano/Coseton, was born in Mexico, as were Mary’s parents. The spelling of Mary’s surname varies from record to record.

A picture of Miranda with her mother can be seen here.

A picture of Miranda’s paternal grandmother can be seen here.

Miranda’s maternal grandfather was William Frank Casey (the son of William John Casey and Mary Cecilia Castimello/Costano/Coseton). Miranda’s grandfather William was born in California. Miranda’s great-grandfather William was Irish, born in Brosna, County Kerry. Miranda’s great-grandmother Mary was Mexican, born in Juárez, Chihuahua. A picture of Miranda’s maternal grandfather can be seen here.

Miranda’s maternal grandmother was Lois Ann Core (the daughter of Robert Herman Core and Ida Marie Bishir/Bishop). Lois was born in Oklahoma. Robert was the son of John W. Core and Birdie Harrell. Ida was the daughter of John Bunyan Bishir/Bishop and Effie I. Jones. A picture of Miranda’s maternal grandmother can be seen here.

Miranda’s distant Bishir ancestors were Alsatian German.

    Wait is she actually 1/8 Mexican?!

  2. Andrew133 says:

    sorry but if 1/8 mexican will change the appearance of some then the vast majority of russians and eastern europeans and finns must look like east asians because all of them have high amount of east eurasian ancestry,and there is no evidence that 1/8 mexican is all native, even mexicans with high amount of native ancestry still they don’t look east asians and they will never pass as an east/south east asians at all, her look could be found in eastern europe, look at this women for example

      The tests are misleading they don’t account for ancient origins. They’re based on datasets that are largely based on self identification. “Are all of your grandparents from this area? Do you know if their parents were from the area? Yes, let’s compare you to others from the other, o, you’re just a minority population, but you’re still representative of what we’d consider local to the area.”

      Human migration is messy, and swapping DNA with migrants is inevitable. There’s pockets of foreign DNA in many populations people think of as homogeneous.

      Phenotypic traits can become altered from influx of ancient admixture. Sami are related to East Asians, like the Yakut and Mongolians, and still share some of their traits, and they in turn passed down genes to Finns, which means that influence has traveled to the surrounding areas.

      A small subsection of Turks have distant relations to Mongolians as well. There’s a large subset of ethnic Russians that definitely have geographically foreign roots.

      Indigenous Americans have, at the very least,ten thousand years of separation, from their Siberian ancestors, plus they may have admixed with Austronesians, and Polynesians, and maybe Africans and Western Europeans, all before the time of Columbus.

      Even accounting for all the messiness, there are generalities. Clines that can be observed. A large number of Western hemisphere indigenous people could be sat next to East Asians and you’d be hard pressed to tell the difference.

        • passingtime85 says:

          Like I said those tests are misleading. They don’t account for ancient genetic heritage. If I hadn’t seen her results next to her picture, I would have assumed Central Asian, such as Uzbek, Kazakh, Turkmen etc. Those people are a product of being at the center of Eurasian genetic swapping, it makes sense why they look the way they do.

          Her roots lie pretty far West for her phenotype, it’s not a look I typically think of for Poland, but I have seen some very atypical Poles, and Slavs in general, proving that just because I have an idea in my head of what a people in a certain territory/region typically looks like, it doesn’t mean it’s representative of the whole.

          I could see a few hundred thousands faces, of any given area, and it probably still wouldn’t mean I’d be able to pinpoint the tens of millions of faces I haven’t seen.

          Most clines are gradient, based on geographic proximity, the further away a people are from one another typically the more dissimilar they look, the closer together, because of swapping DNA, the more similar they are.

          Sometimes a monkey wrench gets thrown into that paradigm, when reverse gene flow happens, or when mass immigration, or a small but significantly prolific group immigrate to a new area.

          It’s happened a bunch of times in the last 50k years or so. Eurasians brought neanderthal DNA back into Sub-Sahara Africa, Mongolians brought their dna, and probably Denisovan dna, to the Anatolian peninsula, West Asians traveled East and mixed with Austroasiatics making South Asians, East Asians went even further East mixing with Austronesians making modern Polynesians, Antolians went West and established roots across Europe but the male lines that founded Iberian populations were replaced by Central Europeans, West Asians replaced the majority the original North Africans, ancient Egyptians used to be extremely West Asian but modern populations have significant input from SSA, on and on, and on, and on.

          Humanity’s diversity isn’t as black or white, beige, brown, yellow, red or pink for that matter, as we think it is.

          That said, I wonder which haplogroups she belongs to, that may help to understand why she’s unique looking.

          Could be a fake. That “Lithuanian” girl looks straight Japanese,rather than Central Asian. Of if real she may be Tatar.

          • Andrew133 says:

            so what about this british woman also ?
            ,is she also Tatar or japanese ?


          • andrew says:


            You dont have to believe to all the stuff you get online. Though atypical looking people do exist, such social media accounts should be verified.

          • passingtime85 says:

            #1 I wouldn’t know what she is, I would guess not wholly European.

            #2 Angles, focal lengths, and distance from subject/object can change the look of said object, so that may not be representative of what she looks like.

            #3 Makeup/cosmetics can also alter appearance a great deal. Not to mention possible cosmetic surgery/procedures may have had a hand in her physiognomy.

            #4 Her results were posted 4 years ago, there’s no telling which “chip” 23andme used to test her sample. More contemporary results could provide possibly different and possibly more accurate estimations.

            #5 Admixture tests don’t account for ancient origins.

          • Andrew133 says:

            I don’t know but, is it difficult to say that both of those two women are just European ??! both of those two women are of fully european descent,they are not japanese or chinese or tatar or anything of that matter, they are just european but with very atypical pseudo-asian look like miranda cosgrove, I could give you many examples of people of fully european descent who look very east asian but they are european, so judging people according to their appearance doesn’t make any sense, the thing that makes you european is not your appearance but your genotype

          • passingtime85 says:

            European going back a few hundred years though.

            How about further back? You can often tell when people look out of place in contrast with their regional/territorial cousins. There’s exceptions to everything but there’s also possible and plausible explanations that people tend to overlook.

            Genotype, haplogroups, autosomal SNPs, whichever metrics you want to use, are still only as accurate, as the people that designate them.

            If researchers think it’s unimportant to stress that certain SNPs are originally from one region, but have been in a newer location for several hundred years, they’ll relabel that group as being native to the area.

            The Iberian peninsula is a good example, their genetic input ranges from 4-20% contribution from North Africa. But they score mostly if not all “European” on admixture tests. That’s because the change in their dna occurred one thousand years ago.

            So researchers and testing companies don’t label them as
            North African/MENA/Maghreb. Only if the person in question has family lines that frequently absorb people with recent significant admixture, into their gene pool, will a non-European designation be warranted. In contrast to families that water down the MENA results with each passing generation, only leaving the haplogroups to tell the tale of their family tree’s origins.

            Origins that again, can be and/or, are obfuscated at the whim of researchers and commercialized results, that are more digestible by the general public.

            Most people wouldn’t understand being called MENA, if their family had inhabited Spain for 1,000 years.

            Yes, judging people by genotype is more accurate, but by which or by whom’s system and methodology are you using?

            Judging by phenotype is much less expensive, less time consuming, less labor intensive, and can almost be done instantaneously and because human physiognomy is typically geographically representative, it’s a fair enough tool, unless you’re looking at a recently admixed individual.

            Judging by physical attributes is the basis of taxonomy, and it can be backed up by DNA profiling, if there’s an established data set from which it can be compared and contrasted.

            It’s just that it’s an area of study that is misunderstood and is a sensitive subject matter to most people, because it’s so closely tied to “race”, which is tied with memories of war bigotry, hate, fueds, war, and strife.

            So researchers make concessions and try to handle the commercialization of this science, in a way to make it as appealing as it can seem, without stirring up memories of the schisms, that have plagued our species since the dawn of consciousness.

            Even professional scientific researchers aren’t informed about deep roots. I once read about a professional anthropologist that couldn’t identify remains of “Latino” skeleton, because the skull didn’t fit what she thought of as “white”, “black”, or “asian”.

            She unaware that Western Hemisphere indigenous people are descendants of East Asian/Siberian migrants. A dentist had to identify the remains for her, and easily identified did so, because most East Asians and their Western hemisphere cousins have shoveled incisors. This trickles down to all people that have “mongoloid” ancestry, it can disappear in a few generations if the descendants mix outside that group, but if individuals keep swapping that East Asian heritage, it stays as an identifiable characteristic.

            You can find anomalies all you want, it doesn’t completely invalidate the concept, that the majority of the time, look commonly ties with geographically heritage/roots.

          • Andrew133 says:

            oK, if you have a European with ancient siberian admixtures and his phenotype affected with these admixtures, do you consider this person European or not ?

          • passingtime85 says:

            Do they still have shoveled incisors? Many people from Scandinavia have Sami heritage and exhibit that feature still.

            Sort of a joke, but it has a kernel of truth in it.

            Yes even with ancient Siberian roots, you can be European, but it’s like the off brand type. Lapps are European, but also they’re a weird little subsection of the population, that kept some of their foreign characteristics. They weren’t completely watered down through cross breeding, they instead closed off influx of new DNA and kept swapping the DNA markers that keep them looking unique. Lapps are European and “whiter” than Yakuts, but they’re less European than Germans.

            Scandinavian vikings had their hand in setting up some gene pools and family trees in/around Europe, it means it’s fairly possible they brought along Sami heritage, which means East Asia, which means atypical genetic links are everywhere the vikings spawned lines, that have survived to this day of course.

            Mostly they should be watered down to the point you shouldn’t be able to tell the difference, but if you get a few lines that share similar heritage continuously interbreeding, you’ll inevitably get distinct subsection of phenotypical traits.

            Europeans as a distinct geographic population is the youngest of all the old world peoples, of the mainland continents. Humans have been in Europe from anywhere from 45,000 years to all the way up 200,000 years ago. But they didn’t start sustaining large communities until herding/farming were utilized. So let’s fast forward.

            Between 10-12,000 years ago Anatolian farmers started branching out deeper west into Europe. They mixed with nomadic hunter gathers that were already present. So are these what modern Europeans are, hybrids neither West Asian nor European?

            Let’s jump ahead again.
            Probably 4500 years ago the Sami experienced a large admixture event and were infused with East Asian DNA, that pretty much altered their physiognomy permanently. Turkic people swept west and southwest over 4200 years ago, leaving traces in Anatolia, ie West Asia. East European men went west and replaced Iberian men 4000 years ago. The Persian Empire reached the Balkans 2500 years ago. The Macedonian empire overthrew them and branched east. A few centuries later Romans swept north, south, east, and west into Europe and brought with them unique markers, that were rooted in Anatolia. Vikings that undoubtedly had Sami heritage, raped and pillaged through the British Isles and Normandy. Normans attacked and subjugated the English, the Angles and Saxons in part took over the isles and in a small part replaced the Picts/Celts/Britons. 1300 years ago North Africans took over Iberia and even tried to push into Gaul. 800 years ago Mongols swept west and left a sparse, but detectable, trace of DNA in their wake along the way, all the way into Russia, and on, and on, and on, all the while many many individuals taking foreign spouses, or victims as the case may be, and swapping DNA.

            Migration ebbs and flows, floods and recesses, and backwashes. DNA, haplogroups, SNPS, phenotypes get altered, replaced, evolve, or go extinct.

            These people were all effected by non-European DNA for at least the past 5,000 years. Probably one of the only groups unaffected overall, would be Basques, they’re as European as you can get with heritage stretching deeper than 5,000 into the history of Europe, probably being descendants of those original Anatolian/hunter-gatherer hybrids. Compared to Basque everyone else pretty much, at least partly, is of non-European heritage.

            So whats the cut off point? Time your ancestors spent in a region, geographic location in relation to known roots, physical attributes, citizenship, a mix of those?

            Idk maybe people should just asterisk/dog ear, areas in their mind. Southern Europeans have North African West Asian roots. Some North Europeans have a touch of East Asian Roots. West Europeans have some East Asian brought by Northern European marauders/vikings, but it’s more remote. South East Europeans might have some West Asian ties. East Europeans maybe related down the line with Mongolians.

            Close proximity and invasion/occupation events, involving separate groups, blurs distinction and reconfigures attributes.
