Found her parents on FamilySearch.com Went to Mary and entered her birth date.
but there was no mention of husband.
The record of birth and death are on the cemetery records of the cemetery I had in prior msg.
I am searching the SMITH line and Mary's husband was Marcus B Smith an executor of William I SMITH (1869 Montgomery Co NY) who Ibelieve is my ggggg father as the probate notice lists my gggg father, Denias, as an heir. I have a researcher in NY checking on this line and she sent me the Mary McDuffee info.
