i am a descendant of William and Elizabeth of Lunenburg County, VA. There are many of William-Elizabeth descendants (or their spouses)who have developed their linkage to William and Elizabeth and have submitted their data to various genealogy data bases. My data came from my now deceased aunt, Nora Anderson of Little Rock, AR. My older sister, Avery Nelson (also of :Little Rock, AR) now keeps up the research. Floyd Smith, whose wife is a descendant,now lives in San Diego County and he has done alot of research on the Lunenburtg County Stones. So has my cousin in Anaheim, Jim Wilks whose son, Dave has established "my-ged.com" homesite for large genealogy data bases. All of our separate research is unfortunately deficient about the roots of Elizabeth Roberson. However, all our data agrees that William and Elizabeth had 4 children (William, Ashley, Elizabeth, and Mary). The will of William (the husband of Elizabeth Roberson)was recorded in York Co., VA(bruton parish). It was signed 25 Nov1729. Bothe Jim Wilks and my lineages down from William and Elizabeth Roberson can be viewed at http://www.my-ged.com
Unfortunately, Our data on the ancestors of William is still a little scant and more research is needed. There is one source at geocities.com that claims to have some dat going back to William's father and grandfather (both of whom are believed to be named William too). Biut some of the data's dates and places in Virginia seem to be different than our data. It just needs to be checked out.
If you are a descendant also, I would like to receive your file and I can send you mine. I assume you have a program that can accept a file gedcom format. I will look forward to hearing fom you.
