I have a copy of a bible record of John W. and Elizabeth Myers Campbell where
the family spelling of Swart/Swartz is listed as SUARTS. It was an 1870
marriage date of a John W. Suarts and Lizzie M. Campbell.
Maybe this is typo as I don't have photo copy of the record (but am trying to
find it) or maybe this is how the family spelling was ... but it might be
another avenue to pursue.
