General Notes
Birthplace from 1880 census for daughter, Matilda (Swallow) Hennis, living in Short Creek, Harrison Co, Ohio. This connection (Mary) is "iffy", but is based on the fact that Mary Hart was living in Athens Twp in 1870, which is next to Short Creek. Mary was born in 1804, which would make her 34 when Matilda was born, and Mary was listed as being born in England.
