The will abstract of George Walker (md Jane Curle) that I've read names a son George, executor, and daughter Jane Crooker. I know nothing about her (except I believe she more likely was a Jane Booker. There were several Booker families associated with this family in Hampton, but I have never come across a "Crooker" name.) The son George sold Nansemond Co. property to Daniel Meade in Feb 1768 (from Hening's Statues, vol 8.). And was married by 1764 to Susan, with whom they buy property from Mary Bell (from Elizabeth City Co, OB). He evidently died by 1787; in that year Susan Walker is listed with 5 slaves and a minor levy, George Walker, in the Mecklenburg Co property list. There is also a Wilson Walker on this same property list with one slave. So he probably their elder son. I wonder if your William Walker might have been the same man (perhaps his full name was William Roscow Wilson Walker?) Or he may have been a younger son born sometime after 1771, and therefore not old enough to be listed on this property list. I have found 2 or 3 possible daughters of George & Susan: Judith Walker md Feb 1789 Lancaster Co, VA to William Westwood Wallace; & Grace Walker who md Jul 1780 to James Wallace & she probably the Grace Wallace who md 2) Dec 1794 in lancaster Co, VA to Reuben Bonwell. Then there is a Malinda Walker listed in Family Search as the daughter of George and wife to an Edward Mitchell who left VA & died in Illinois--she might possibly be of this family as well. Whatever data you can share on your William Walker would be helpful and I will compare it to what I know of this family. Thank you.
