I am looking for any information on a Mary Pearsall Westlake, from upstate NY. She would have been born around 1848. She married Dudley Lamentine James about 1890 in New York City. In 1891 they had a child Elmer Lamatine James born in New York City.

I have no other information except that something happened to the marriage, as Mary raised her son by herself and Dudley wen on to other things and fathered my grandmother by a different woman. I know he had no contact with his son as my grandmother was 15 years old when she found out she had a half brother and she was waied by her father Dudley.

This is a brick wall in my tree and I would love to break through this wall. Any information would be appreciated
