Hi Brigetta,
I know the house you speak of very well. It is derelict now, and is on that sharp bend. I will take a photo of it sometime for you.
On your ancestory, I have located the following Heneghans in Lissybroder (which is the documentary name for Louth Lodge; Quarter is the neighbouring townland).
These are baptisimal records from the Catholic Parish of Dunmore, records are on microfiche in the National Laibrary of Ireland in Dublin.
July 29 1838 Brigit Heneghan, parents Denis & Mary (Mullin)
Apr 28 1838 Mary Heneghan, parents James & Brigit (Lyons)
Jan 18 1834 Peter Heneghan, parents Thomas & Brigit (Lyons)
(Townland for this last record I think is Lissybroder, but is very smudged, almost unreadable).
I hope this may be of value to you.
Chris
