Have you found anything on your Margaret Edel? I also have a Margaret Edel from Philadelphia on my tree, but I don't think it is the same one. My Margaret Edel would have been born abt 1804 in Philadelphia. She married John Stamford (also of Philadelphia).
Since there were a few Edels in Philadelphia in the late 1700s, its hard to pinpoint which family my Margaret Edel would belong to. I was hoping that you figured out who your Margaret Edel's parents were so i can eliminate that family...
Please let me know.
