The death certificates of James Richard and Margaret Ann Findeison show Charlie Findeison and Margaret Ann (Maggie or Mary for short)Stephens as their parents. I just called mom, and now she is not sure of which cemetery she stood in now. I have been to the Pittman cemetery and while there are several graves without names on them - there is not one for Frank and Maggie. They could have been placed in the Stephens Cemetery.
I think your findagrave info looks great.
