Samuel Lambert/Lambeth 1740-1819 moved from Maryland to York County, South Carolina around 1790. His son John Lambert or Lambeth married there in 1796 (marriage date and children's names given in his sister's widow's pension application) and based on family legend his wife was named Mary.
I have a DNA match of 15+cm (on Chr 20) to 6 different gedmatch users. Four of the 6 have known Robertson/Robinson ancestry, and 2 have traced that line back to York, SC. I'm speculating that my Mary unknown may have been a Robertson. Does anyone have any info on Robertson/Robinson or Lambeth/Lambert lines in York County SC around the 1790s?
Thanks for any help,
