What a find!
My great grand dad William A. Beck, known to his family as Will, was born 16 March 1877, married Leafy Forest Delano in Praire Grove, Washington County Arkansas 15 July 1897.
They had ten children. While I don't know the birth order -- I am told that Gordon Buford Beck SR born 27 Sep 1901 was the oldest male. He took care of his mother after the death of his father which I'm told was when he was about 15 so that would make Will's death date be about 1916.
Will's children are:
Gordon B Beck Sr.
Stella (and I think that it was Estella or something)
Robbie or Robert
and the youngest as least youngest brother is Lewis who died in a car wreck. One or two of the wives are still alive. but the children are all dead. Gordon, my grandfather, died in Chickasha OK in July 1974.
As you note in your posting, Will had a brother Lewis. I believe this is Lewis Otho who married (Leafy Delano's sister) Rozella Delano 5 July 1896.
