Mercy/Mary Tiffany born about 1786 in Connecticut married David Sinclair, he probably born Newmarket NH c1786. Mercy and David living Ausable, Clinton Co., New York in 1850 (census), later in 1860 living at Lowell Vermont. They had two children that I know of; Clarissa and Roswell. Mercy and David may have died at Lowell, or perhaps Essex, Chittenden Co., VT, most likely between 1860 and 1870. Hoping to find Mercy's parents and any other detailes regarding her and David Sinclair and their family. Thank you Janice
