Julia Stiles is an American actress.
She is the daughter of Judith Newcomb Stiles and John O’Hara. Julia’s father has Irish ancestry and Julia’s mother has English and German roots. Julia is married to camera assistant Preston J. Cook, with whom she has a son.
Julia is sometimes described in internet, and other, sources, as having Italian ancestry on her mother’s side. It is pretty clear that Julia’s mother is not of Italian descent. It is not as clear if Julia has any Italian ancestry on her father’s side.
Julia’s paternal grandparents likely were named John J. O’Hara and Ethel H.
Julia’s maternal grandfather was Meredith Newcomb Stiles, Jr. (the son of Meredith Newcomb Stiles and Katherine Elizabeth Toof). Julia’s grandfather Meredith was born in Buenos Aires, Argentina, to American parents, of Colonial American (English) ancestry. Julia’s great-grandfather Meredith was a journalist, and was the son of William Curtis Stiles and Mary Allen Arey Newcomb. Katherine was the daughter of Franklin Pierce Toof and Mary Isabelle White.
Julia’s maternal grandmother was Ruth “Randy” Hunsaker (the daughter of Albert Hunsaker and Dorothea/Dorothy E. Deroner). Ruth was born in New York, and had German and English ancestry. The Hunsaker and Deroner families in Pennsylvania originate in Germany. Ruth’s parents, as well as her maternal grandparents, William E. Deroner and Katie E. Seagreaves, were all born in Pennsylvania. William’s parents were Moses U. Deroner and Amanda Fink. Katie’s parents were William Hamilton Seagreaves and Annie E. Weaver.
