I am looking for the Parents of my 3rd great grandmother, Mary Clay. She was born about 1793 and died about 1830. On 7 Jul 1819 in Roxbury, Mass she married Isaac Brackett (1791 NH-1885 VT). Isaac married a second time after Mary's death to Susan Green. Isaac was a farm and resided in Stowe VT. Can you help me with more on Mary Clay?
