Congratulations, Pat, on finding your Martha J. Poythress' marriage license for marriage to Edward Neal in Greenville Co, VA on 12 Mar 1880. That is not a marriage I knew about before, and I likewise did not previously know of the 6 Oct 1873 one for James H. Poythress & Eliza Spencer, or any others from Greenville Co, so I do indeed look forward to any posting of others. My accumulated Poythress data only has one slim possibility for help on the William Poythress who fathered at least the above James H & maybe also the Martha J, along with mother Julia: From emails back in early 1999, which I am sure were to the Poythress List, I had entered the marriage of James R. Portis/Poythress to Sarah Crowder in (not distant) Northampton Co, NC on 13 January 1827, along with a list of their children. The 2nd child was a William, about whom no further info was given. The emails I noted were on 2/3/99 from Jean Poythress Spille (now Jean Poythress) and on 3/29/99 from Lynn Poythress. They would've had to have had son William pretty quickly in order for their William to be father of James H & Julia. Seems like we had some messages about Poythresses in one or more censuses in Greenville Co, Va, at some point, too, so you may want to check the Poythress-List Archives for that info, too. Good luck on finding further information on your ancestor - Barbara Poythress Neal
