Searching for info/descendants of William WALKER (age 67 in 1920) and Lydia VALENTINE WALKER (59 in 1920) originally of Shelby County, Illinois. They were in Missoula City, Missoula County, Montana on the 1920 census with their son Clifford S (39 in 1920), daughter-in-law Harriett, and grandchildren Lawrence G (13 in 1920), Norman S (12), Walter A (10), Kenneth B (9), Esther P (6), Lillie M (4). William and Lydia also had daughters Edna, Lonie, Ida, and Effie. Did these daughters marry, move to Montana or stay in Illinois? Any information appreciated.
