Hi..I am trying to do a family tree myself..it's so hard to find out who's who. But I did find my great-great grandma's name is Sarah Mariah Gulliver. Her maiden name is Lawrence. Don't know when she was born. She married Aaron Jackson GUlliver on May 23, 1844 in Allen County Ohio. There son is Edward Emberson Gulliver..my great grandfather. Don't know if this is her.
