Henry Mills joined Friends at Hopewell in 1782. During his membership there, he married Elizabeth John and served as an overseer of Middle Creek Meeting. He and Elizabeth had their membership transferred to Westland in 1787; during their move to Washington County, Pennsylvania, their daughter Mary Mills (listed on their certificate from Hopewell) died.
Henry Mills lost his membership in 1817, but the minutes are vague about why. He died circa 1829.
