My ancestors are from County Antrim, Belfast area. Daniel Drennen died in 1758 and never made it to America. Four of his sons were here on or before 1770. They were William, Thomas, John, and Hugh. They settled in PA just outside of Pittsburg, in Elizabeth Twp, Allegheny Co..
From there their descendants migrated to Illinois, Ohio, Indiana, Kentucy, and Arkansas.
I have quite a bit of data and am willing to share with anyone interested.
