Arnestown is a Townland 1-2 k south of New Ross, in the district electoral division(DED) of Ballymitty, in the civil parish of Bannow. It it also close to Wellington Bridge. A Townland is the smallest -and the most ancient -Irish landdivision. If you wish to look up the Irish census -1901 or 1911 ( irish census.ie) you will need the above infor: ie, county,DED and Townland. I think the church and burials would be in New Ross or St Peters Church, Ballymitty. Also look up google maps.
