Dean Cain is an American actor, producer, writer, director, and television show host. He starred as Superman on the T.V series Lois & Clark: The New Adventures of Superman. Dean is the son of Roger Hugh Tanaka and actress Sharon Thomas. He was adopted by his stepfather, director Christopher Cain (born Bruce C. Doggett).
He has said, “I’m mostly Welsh, and then one-quarter Japanese, Irish and French Canadian.” However, Dean’s father was of three quarters Japanese descent, making Dean of three eighths Japanese descent. He also has English ancestry.

Dean’s paternal grandmother was Grace E. Miyoko Sugiura (the daughter of Joseph Tadashi Sugiura and Eva/Evangeline May Frost). Grace was born in Washington. Joseph was born in Hamada, Shimane, Japan. Eva, who had English, Irish, and French-Canadian ancestry, was born in either Wisconsin or North Dakota, and was the daughter of Frank Leslie Frost and Ida Mae Forsythe, whose father was born in Cloughmills, Antrim, Northern Ireland.
