I'm Earl's grandson, Keller Wightman. He had 6 children; Roberta, Marilyn, Mildred, Dorothy (my mother), Warren and Corrine. Marily (now Kempke) and Warren live in Blair Ne. Dorothy (now Floyd) and Millie (now Nisco) now live in the Seattle area.
Always knew Gus as "Cuss" - that's how it appeared on Grandpa Earl's birth certificate, also how several of my cousin's referred to Earl. Never could figure out how he came by that name.
Believe that Aunt Ruth was childless, don't know much about the other siblings. Would be glad to obtain specific info for you if you'd like.
