My grandmother's name was Laura Viola Pierce D. 1973 but she was born in Bastrop County Texas, and lived her life in Texas. I know of no connection with Michigan. Her father and mother were from Mississippi. The name Viola is unusual. It could be part of the family that went north from Tennessee or Mississippi. If you could scan the picture and send it to me at Brkwork@AOL.com
I can see if there is a resemblance.
