Sometime after that May 2013 post, I found a newspaper obituary for William W. Watson in 1874 that gave his place of birth as Morristown, NJ. I also found a book online of the History of the First Presbyterian Church of Morristown and found Watson and King entries. I suspected from those records that Thomas (1761-1812) and wife Charity Watson(1771-1842) might be the parents of our William and sister Charity. Carol Powell replied in another forum with this link: http://www.pcmorristown.org/who_we_are/our_history/w_alpha_grave_yard/http://www.pcmorristown.org/who_we_are/our_history/w_alpha_grave_yard/ Now I see an "ED. Note" in that church's cemetery records that confirms they were parents of Charity Watson King. Not a solid source but a great lead. I also found an Elizabeth and Harriet Watson in Morristown who I suspect might be the other sisters who survived William. Great progress on one of my research brick walls!
