Many families from Clark and Jackson Counties in Wisconsin had a "pathway" to South Dakota, Castlewood area circa 1870's/1880's. I have an old letter from M.M. Staley from Watertown, Codington Co., S.D. dated 1978 when I first started tracing the Shanks' family that settled in Clark County and he mentions "David Shanks was a lumberjack, as were many of them and came out to the Dakota Territory about 1880 and filed on a homestead, which was then turned over to the Keators. The Keators were lumber people and had mills at Moline, IL and camps in Wisconsin. Mr. Staley's grandfather, William Marshall was a river foreman and came out to the Dakota's in 1878 and built up the Keator ranch which was the land that was homesteaded by these fellows from Wisconsin. The men worked at the ranch in the summer and back to the woods in the winter." He mentions a book with the name "William Marshall Keator D.T. 1882" on the cover. William Marshall married Mary Shanks who was a sister to David. Their father, Hugh and mother, Mary (Galloway) Shanks were early settlers of Clark County, Wisconsin. David's son, Leonard was born in Castlewood, Hamilin Co., South Dakota October 28, 1880. His mother was Isadora Babb. Not long afterwards they headed back to Clark County. I have most of the children, spouses, and some descendants of Hugh and Mary Shanks. Perhaps this will help someone. Does anyone know of the book on the Keator's? Will be happy to exchange information.
