Thank You! It will correct source mismatches. William Russel Sullivan was the grandfather I never knew. My mom thought she was the daughter of the man who married her mother. She never knew about William Russel Sullivan. A cousin that I talked into DNA testing to help find my grandfather's family proved that she was tied to my grandfather, but I was not. More DNA research and regular genealogy found half siblings to my mom, proving William Russel Sullivan was her Bio Dad.
