Okay, I don't know if this is 100% right. The man sitting to Bert's left is William. Lola, the oldest daughter is in the circle. I do not who the girls are. The man on the far right of the picture is Charles (my great-great grandfather). So that means the last remaining boy is James (front middle). I pieced this together from Census records and the fact that Charles was born in 1870 and Bert, Lola, and William were all older.
