Though I am primarily a Dewees researcher, I have seen some data posted (so the facts or documentation may be suspect) that states "Edward (b. 1739) Uptegrove was the son of William and Sary Uptegrove. My document of William's will, however, only shows two children (Sary and Mary). William Uptgrove had a brother John Uptegrove, whose children I have yet to place. Perhaps this is where Edward may fit in? It may be worth the effort to find these children of John and Sarah Uptgrove. The fact that these dates, places (Kent County, DE), and names are close, this would seem possible. I only have William's will, and perhaps a search of John's will may disclose the other children.
