Patrick Furlong was married to Mary Furlong, both same surname. Mary was a sister of my great grandfather Charles Furlong who lived a few doors away on Swan View, The Faythe (although his house was sometimes listed as Castlehill Street. Castlehill Street is now Kevin Barry Street. I can id both houses on Google Maps/Earth if you like.
Mary and Charles were the children of John Furlong d.1887 and Anty Kavanagh b. 1835 in Castlebridge, d. 1905. Both Anty and John died in Distillery Road, Wexford Town.
Hope this helps. I have a bit more on my MyHeritage site, "Kehoe Mac Eochaidh". Feel free to look. I only have one photo of Charles, which might be of interest.
Regards, Gearóid.
