Susan Marie Fisher

I am looking for a needle in a haystack. I have a Fisher relative that is/was born in the early to mid 193's who's maiden name was Fisher. Her first name may be Marie, or another "M" first name. From the vague into we have, she has passed away and is buried in New Jersey. She was in New York for a period of time during the 1950's and had a baby girl out of wedlock. Information stated that she had a difficult life. I know this is vague, but no one remembers any details.
