I have just begun to search my grandmother's family tree. The Cummings. Her name was Ruth May Cummings, I've heard it said she had come from Missouri. She had a sister named Elvie. I believe their father was W.W. Cummings.
My grandmother was born in the early 1900's and married Bill Mathis (the first time). The Mathis' and Cummings (including her father) wound up moving to East Texas in the early 1900's and all passed away there.
