In answer to your question, "Was this part of Sarah Alice's family ?" But first I want to thank you so much for all your helpful information. I'd appreciate any other information that you can share. (I'm just beginning to research my grandfather's family.) Yes, I believe that her brother was my great-grandfather, William Anson (W A) Graham who is the father of my paternal grandfather W T Graham. W T Graham's siblings were: Lela O Graham 1903 TX
Myrl A Graham 19 Dec 1904 TX - May 1985 Silverton, Briscoe Co
Walter A Graham 1908 TX
Homer A Graham 1910 TX
I believe that Lewis Graham was a brother of W A Graham and the father of M B Graham. M B Graham was married to Polly; their children were Betty Graham Ferrell and Bobby Graham who was killed in an auto accident.
