I think I can help. James Traina is my uncle. He had 3 siblings Roy, Stella and Millie (he was the youngest).Although they may have been married in Elizabeth, his mom and dad lived in Cranford (Millie and her husband Bill Joyce lived next door). I was born in 1950 (I'm his brother Roy's oldest son)and remember Grace (always called Gracie). How old are your half brothers and sisters? Tell you the truth I didn't know my grandmothers maiden name but my grandfathers name was Jim.I remember meeting Jim's kids when I was small but they moved to Florida. FYI Jim was always called Chick by the family.
