Have you come across an Armstrong S.H. Martin born in SC or maybe NC in 1825?
His family has McDuffies, Jackson, Foxworth, Carmichaels, Strickland, Hardee. There were many Scottish families in the area of Dillon and Marion County, SC in the 1700-1800s.
Most of these migrated from NC to SC in the early 1800s or maybe sooner.
