The records of St Johns and St George Parish as documented by Peden documents this birth.

A Lewis Potee Jr. died before 1760. His estate accounting was filed by William Norris, Administrator, 12 Feb 1760 and he stated “there is no widow, only 1 brother and 2 sisters”. I’m not sure who he would have been. While it’s possible James and Elizabeth had additional children, I don’t know that, and so the facts seem to fit this Lewis.
