That death record in Parsonstown, he was from Ballygaddy, Kinnitty, I checked the rootsireland record, it didn't say who was the informant only that he was married. He is the son of John (Jonathan and Johanna McGrath.
I went to find his marriage, he married Mary Davis in 1877, but, it says that his father was George, but he was from the same place Ballygaddy.
