Have you had any luck on Graham family since you posted your message Oct. 2001? I too am looking for information on Graham family in Kansas & MO. My grandfather George Gerald Graham was b. in 1898 in Joplin, MO but his family moved to somewhere in Kansas right after his birth. His Father was John Graham and Mother was Cora Allen/Graham. Don't know if these families are connected. John could be brother to your William.
