I don't think we've ever exchanged information, but I would enjoy hearing from you, as William was an older brother of my ggggfather, John.
I have visited the East Newbern Cemetery and saw many of the Gillham graves there, including William's. I also visited the Dow and Newbern Cemeteries and saw a lot of the Lurton & Lofton graves, but as I am concentrating on Gillhams I didn't pay too much attention to them, although I do have a lot of Lurton/Lofton information in my database.
I use Family Tree Maker, version 8.0 as my database, and I have about 40,000 names in my database, 26,000 or so who are either direct descendants of or kin of descendants of Thomas Gillham, Sr..
I'll look forward to hearing from you.
