Place of Birth: Los Angeles, California, United States

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

Miranda Cosgrove is an American actress, singer, and songwriter. Her roles include School of Rock, Despicable Me, and the series Drake & Josh and iCarly.

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.

Miranda’s maternal grandfather was William Frank Casey (the son of William J. Casey and Mary Castimello/Costano/Coseton). Miranda’s grandfather William was born in California. 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). Lois was born in Oklahoma. 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 German.

    “1/8th mexican” LOL mexican it’s a nationality, Mexico is a new world country. This is the same thing as saying “1/8th american” or canadian. It does not make any sense. Of course there are countries outside the Americas where nationality and ethnicity are not the same thing, even in some european countries. But it’s especially silly to put a new world nationality as if it was a legit ethnicity, unless there is strong evidence sugesting her ancestors from mexico were all native. But i highly doubt that.

      What constitutes a “nationality” and “ethnicity” is not set in stone though. if you ask many Americans of Mexican descent what their “ethnic background” is, I bet many would say that they’re Mexican or Latino or something along those lines.

      Anyways, if Miranda is only 1/8th Mexican, then she’s probably no more than 5-10% Amerindian at the very most. Interesting how she looks very Amerindian influenced though.
