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 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.

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.

    I believe her paternal grandparents were Joseph Christopher Cosgrove and Florence Cosgrove. Joseph was of Irish descent being the son of Christopher Joseph Cosgrove and Elizabeth Walsh. Florence was Romanian Jewish.

    Her paternal grandparents are possibly Joseph C. Cosgrove and Dorothy Stevenson. I think her father was possibly born in Louisiana.

    This is Joseph’s death record:

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

    Bishir can’t be a European surname.
