Not too sure whether this relates to my Mary Ann Monford's family but she married Hugh Henry some time around 1823. I have never located her actual origins but the HENRY family have links with Ballybay in Monaghan about 1824 and were in Donegore, Antrim in the later 1820s until they left for England in the late 1840s.
Anyway this site is useful for Hearth Tax returns in Antrim 1669.
