I am looking for information on Margaret Breckenridge, daughter of James Breckenridge, b. c. 1655, and Jane Austin. My information indicates that Margaret married a man named Allen and that she had descendants in South Carolina around 1819. Margaret had brothers: Alexander, John and Robert. They were born in the latter half of the 1600's. I have no d/o/b for Margaret. If anyone has any record that can fill in any blanks here, it would be appreciated.
