spend some time checking around and found that these were indeed the parents of Manette.Lucked out on the 1930 CA census, Manette's daughter Wilma is listed twice. Once with her Frank parents & once with her Floyd grandparents; Isaac & Mary F. Floyd living in LA county. She is listed as Wilma F. Frank. Also in the 1930 Floyd household is last born child Reginald Floyd 22 bn in Florida.
I found Reginald's Calif Death record and it has his mother's maiden name on it.Sooooo, this would also be Manette's mothers maiden name. I tracked Isaac Floyd over the census years and he always has the same wife.
