Bill, you have a question mark beside the marriage of John Lowe to Mary Hawkins. The information below should provide a pretty clear answer. Mary Hawkins made a deposition re: George Tubman in PG County June 12, 1755 at which time she was said to be 74. That would make her birth date 1681 which would make that particular Mary a little old. John Lowe and his wife, Mary, of Prince George's County, MD conveyed on May 3, 1727, tracts of land each side of Portobacco Fresh, 330 acres. This land was given by Henry Hawkins, late of Charles County, to Mary Hawkins, his natural daughter and now Mary Lowe, wife of John Lowe. (Land:L#2.355) Ann
