Hi Larry:
It looks like your Mary Harding was born the 29 May 1782 - died 1863 and was buried in Merion Friends Burial Ground, Montgomery, PA. I think she was the daughter of Esther Bond and Abraham Harding.
Mary married Abraham Richardson who was born in England. They married about 1810 - probably in Bucks County. They had 7 children: Anna, Benjamin born 29 December 1812, Alexander, Abraham, Lemuel, Mary and Robert. I believe Abraham died about 1840 in Merion, Pennsylvania. Your Benjamin may have moved to Tennessee and married there. Perhaps a Lucinda Garrison.
This family is covered in a book by George Norwood Comly, Comly Family in America, 1939, page 120 that provided information to the Jeanes Family tree.
I sure hope there is a hint here for you.
Ann Carmel
