Hi John, Sorry it took so long to get back.I spell my name Carlile,but it changed back and forth in the 1800's.Off hand I can't find a connection between your family and mine unless it was before 1800.David named his 1st son Alexander and 1st daughterMary.Tradition was to name 1st son after your father and 1st daughter after your mother,so two of the people I have looked at were Alexander,1790 Georgetown.SC census and Mary 1820 Char.SC census.They are approx.the right age
