Marriage record of Samuel Ashcroft and Mary Rudd, 1764, Parish Registers of St. Mary's Church [Church of England], 1584-1901, Stockport, Cheshire, FHL Br MF 2146002, Page 185, #53.
Both are of the Parish of Stockport in the County and Diocese of Cheshire. Married by banns. Day of marriage looks like the 23d, but the word "third" is smudged. Samuel signed his name, Mary signed with her mark.
No other record of a marriage between a Samuel Ashcroft and a Mary has yet been found that matches the time period and the area.
