Merrick7 ... yes ... I did received this before, and it was VERY helpful.
My husband's great-grandfather was Simon Armstrong, working in Cashel at the time of his marriage - which showed his father to be "James Armstrong - Farmer". There were only 3 James Armstrongs in Griffiths, and only the one in nearby Ballagh was renting any notable land and fit the "farmer" description.
Seeing this grave marker enabled me to confirm who I SUSPECTED was one of the children of this James Armstrong "of Ballaugh" (but could find no birth or baptism record for) ... the James who died in July 1912 (and his wife Catherine, nee Brien, who died in 1913 - missing from the copy you just sent, but shown on the original).
This younger James named a Simon Armstrong as one of the baptism sponsors for his 2nd child ... and Simon reciprocated when his first son was born ... which made me feel fairly confident that James Jr and Simon were brothers.
The grave stone provided evidence of the connection James SENIOR to James JUNIOR ... and the latter provided the link to Simon.
The one thing that I do find curious is that there is no reference to James SENIOR (and his wife, Mary Mara) "of Ballaugh" actually being buried in the same plot (although obviously subsequent generations used that grave). James Armstrong (SENIOR) died 12 July 1877 (and his wife, Mary Mara, before him on 16 March 1867). I went through all of the other gravestones detailed in the cemetery ... but could not find them buried anywhere else. I suspect that they are in this family plot, however it is just not marked on the grave stone.
I am wondering - is there a particular Catholic Church nearby connected to the Clonoulty cemetery that might have any additional records? And would that be the church that people from Ballagh in the 1800's would have attended?
Thanks for all of your (and other Roots Chat members) help! There is no way I could have pieced this scenario together without input from all of you from "across the pond".
