There is no authoritative treatment of my line of descent from this family in print. The PDF essay linked below summarizes my research in documentary sources on this family. Although I necessarily pursue only one child in each family, I also attempt to provide basic chronological information on all of my ancestors other children and their spouses.
No additional information on the Cowper family is available at this time.
