In yourHAWLEY book, Rsh. 4, you indicate a birth for Mary Hawley, b. 1762, m. William A. Athey, b. 1742, and that they lived in Prince William Co, VA & Fairfax Co, VA. in 1764.
In 1764, Mary would have been 2 yrs old.At the time of the birth of James Birch Athey, b. 1773, Mary would have been 11 yrs. old.
That would seem to lend more credibility to my contention that this Mary Hawley / Halley was married to Thomas Long, b. 1764.By the time John Hawley / Halley wrote his will, Thomas Long was dead, and John's daughter, Mary Halley Long, was married to Hanson Stone Athey / Athon.
