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.
