My Great Grandmother was Mary Ackerman, she married a Jacob Vanderwall, not sure where? They had 5 children, Mary A., John, Raymond, Madeline, and Marion. They lived in Rochester, New York(Lived at 57 Gorham St and 39 Oakman Rochester, New York). I think I have found a picture of Mary Ackerman's mother in our family picures but do not know her name. Looking for family history can you help?
