Looking for the Family of Donald Wallace of Massachusetts

I am sure they are probably not related. But I am trying to research the family Wallace my sister married Donald Ray Wallace. His father was William Wallace and his wife Grace was a tatum, they were from Texas. I think William wallace who went by Bill, his father was a wallace and his mother a polk, I think. She doesnot have any information but would olove to have any for her children and grandchildren. Darlene Turner
