I found a Francois Lafon at the French Episcopal church (formerly St. Mark's Chapel), Bristol, England in 1719, his wife died June 1720, daughter Elizabeth died Feb 1719 (less than a year old). He had a son Matthias that was baptized earlier there. This was donated church for French Protestants that closed around 1728. A Francois Lafon came to New France/Louisiana in 1719 from Lyon, FR, he was listed as a "vagabond" - shoemaker. I doube that these two are the same person - and don't know which Francois Lafon came to Virginia and left a record dating 1748 in VA.
