My great, great grandfather was George M. Glenn who was born in 1794 in Laurens County, S.C. His parents were David and Elizabeth Glenn. The heirs to David's will (of which David's brother Francis served as its administrator)were his eight children: Anna, Rebecca, Elizabeth, Jane, JAMES, George M., John and David.
According to my grandmother's notes, David was one of three brothers that travelled with their father from Ireland to South Carolina after the death of the mother/wife. She was under the assumption for years that we were Irish. However, it seems that this branch of the Glenn family began in Scotland in the 1100's, migrated to Ireland in the 1600's and then to the U.S. via South Carolina in the 1700's.
