This is my first look at your list, and I am truly impressed. I have been researching the Dewees Family for many, many years, and am aware of the "Original-13" members of the Vessel "Concord". Our John Dewees, a revolutionary in Kent County (b.1749) married Mary Updegrove (parents Uptegrove), in Misspillion Hundred, Kent County, Delaware. The Dewees', too, were Dutch, and Religeous Reformers. They first settled in Germantown, PA and moved to Delaware. Mary's parents were William and Sary Uptgegrove, also of Delaware.Her grandparents were Isaac Op den Graeff (1693-1747) and Rachel Litton, great grandparents, Herman Op den Graeff (ca. 1642- 11/7/1708) and Deborah Van Bibber (1660-1727). I have much of the old Op den Graeff history. What I would like is any information on her parents (William and Sary) and siblings (Isaac & William). Mary moved to Fayette County PA with her family and died November 5, 1818. Her husbands family came from Amsterdam where Adriaen Hendricksz de Wees was born ca. 1585. The family descends through 1) Hendricks de Wees (son) 2) Gerret Hendricks Dewees (grandson who immigrated to the States) 3) Lewis Dewees (great grandson, who married a Mary Wheeler, ca. 1706 in Philadelphia - Old Germantown) He learned weaving from Mary's father, John Wheeler. Lewis moved to Kent County, Delaware. 4) Samuel Dewees (great-great grandson, who had at least 4 children, Joshua, John, Samuel, and Isaac Dewees - all fought in the Delaware Line - Kent County, Revolutionary War) 5) John Dewees b. 1749, great-great-great grandson who married Mary Updegrove. John and brother Joshua moved to Fayette County PA. After Mary's death, the children moved into what is now West Virginia. Thanks for any help ahead of time. John C. Dawson
