Has anyone been able to go further back than Henry McGlothlin, who had a son Thomas E (who married Mary Bennett/Bonnett) who then had a son Henry (who married Nancy Snider) and Thomas Jr (who married Josephine Anderson)?

I've read all the posts to date, but can't seem to go further back.

I am the daughter of Harry mcGlothlin, who was the son of John D McGlothlin (Poppy), the son of Thomas Jr., the son of Thomas Sr, the son of Henry.

Does anyone know the oldest Henry's wife?

Any info will be appreciated.
