I have no further info on the Daniel Coleman, who was born about 1730/1 in Amelia Co., VA. Have you seen the booklet "The Robert Coleman Family fro Mobjack Bah VA to Reno, Nevada and Hollywood" by James W. Coleman" ? There might be some clues in it for you. I only have a few pages copied from this book.
The name of Scotty is a nickname of my middle name of Scott, which was my maternal frandmother's maiden name. That family originally settled in Braintree, Mass. bef. 1640.
