Miranda Cosgrove

by ethnic on December 14, 2009

Birth Name: Miranda Taylor Cosgrove

Place of Birth: Los Angeles, California, United States

Date of Birth: May 14, 1993

Ethnicity: Irish, English, French, 1/8th Mexican, some degree of German [including Alsatian]

Miranda Cosgrove is an American actress and singer.

On her Twitter account, she stated:

I[‘]m Irish,English, and French. People always think im 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 J. Casey and Mary Castimello/Costano/Coseton). Miranda’s great-grandfather William was Irish. Miranda’s great-grandmother Mary was Mexican. 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). Robert was the son of John W. Core and Birdie Harrell. Ida was the daughter of John Bunyan Bishir and Effie Jones. A picture of Miranda’s maternal grandmother can be seen here.

Miranda’s distant Bishir ancestors were Alsatian Germans.

Rose Leslie has the same ethnicity and looks completely different. I think there might be something else apart from the Mexican.

She was asked on twitter several times and she said IRISH, GERMAN RUSSIAN and those countries

why she lied?

Bishir can’t be a European surname.

They are a German family. Alsatian German to be exact.

She must be mixed race being part Irish. Like you said earlier, “To me you are not white” to someone who is half Irish.

after all the years you hated me and wrote i should be banned from this site and i cried and said no she must be asian or mexican

and now we all can see

1/8th mexican

Banned? I think you should be promoted on this website, or at least be an administrator. You were right all along that Miranda Cosgrove is 1/8 Mexican and I idolize you for that. You’re the best genealogist I’ve ever heard of. Please, make us a long list of every celebrity on this website from most Turkish looking to least. You’re the man @Neiltennant keep up the great comments.

neiltennant June 21, 2017 at 2:20 am

No i was never been banned

but some people said here

THIS GUY IS CRAZY HE CLAIMS THAT SUMMER GLAU looks asian

he claims that Brandon Urie looks asian

he claims that brooke burke is asian

in the most cases i was right

bearboy June 21, 2017 at 10:14 am

I am agreeing with you, you are right and should be made an administrator of ethnic celebs. I am not doubting you on this but mind sending a link to where she said she has Russian ancestry only because I can’t find it.

WHAT COMES NEXT ?

ROSEANNE BEING HALF CHINESE ?

bearboy June 21, 2017 at 12:51 pm

Yes, Chinese ancestry is very common for Ashkenazi Jews like Roseanne Barr.
