Isaac Martin, Sr., of Halifax, VA - Establishment of Caroline County, 1728

You make a good point. But note that Isaac patented 2 parcels of land in 1720 on Beverly Run, which is wholly contained by present day Caroline County, and in fact defines the southeastern border of the county. So Isaac was "of Caroline County" once the county was formed. before that, he was "of King and Queen County". It seems more correct to me to list him by the latter county name since the former is implied.

Thank you, Andy. Unfortunately, I can't open your link for some reason. If you don't mind, could you check for a typo?

the link works for me if I open it from the geni discussions page. It doesn't work from the geni email notification where it gets cut off.

Thanks, Andy. That's a very useful site!
