Skillman Family Genealogy Forum
Wonder if these people are related to Randall Skillman mentioned in Bill Skillman's SOA. Randall had two wives, Maria Stryker and later Magdalena Voorhees Stryker. He had children by both women, however, the second wife, after he died, married William Brown Hageman and moved to Illinois.
By her he had three sons and a daughter. I have accounted for two of the sons who moved to the Nebraska area, but one son, David Bayard Skillman, is unaccounted for. This couple possibly be your missing link.
