Update:
It seems that William Richardson Cain(1890-1946) was married three times. First to "Bannie" Irene Hyman.They had 5 children.Second wife was Eleanor Bateman..no children.
Third wife was Bernice Grier. Bernice and William had 5 childen and two of these were twins.
Still looking for the parents of Bernice Grier Cain.
Was she somehow related to Addria Lillian Grier? Addria married George Preston Dennis.Bernice named one of her sons James DENNIS Cain...
