There are a fair number of Ashtons in Trinity Oxford Church in Phila., all through the 1700's. I haven't gone any "newer" than that because the line splits in 1775. The LDS church has 2 films for that church. Let me know if you would like the number and I'll send it to you. This may not be a geographic area that you are interested in. I have a copy of a will from Phila. of Isaac Ashton, November 1809. He names his son and daughter Jonathan and Mary. This is after your Mary would have been married, though. Marilyn
