Ann Arbor MI in the late 1950's...

Now, my mom doesn't want me to do this but I thought I'd give it a shot. My grandmother's maiden name was Paula Painter. She had a child in her teenager years, putting that in the mid to late 1950's. She lived in Ann Arbor, MI and had two brothers. The conditions of her adoption were extremely taboo, so unfortunately the rest of her family members never revealed much more to us than this before they passed. If this sounds like anything close to who you are looking for, feel free to message me =]
