Probably can be of help to folks looking for Sharon/Sharron/Sharran that came from Scotland via Northern Ireland. Two brothers in Chester Co PA by 1727, Lancaster Co PA by 1840, Cumberland Co PA by 1750, Mifflin and Juniata Counties by 1770. Then by 1800, branches of the family spread into Ohio, Kentucky and then Illinois. One branch went to Ontario about the same time. Small branch remained in Mifflin and other counties in mid PA.
Also have info on the English Sherran (pronounced same way as Sharon) that came to New Jersey in the 1700s and settled in Fenwick's Colony there.
Give me some clues, I can probably help. But, have no info on any lines that came to America after 1725. There were lots, mostly Irish, some English, found one that was German.
