Oh, thanks so much for all of this info. Looking at this, I see they already had a son called Michael born 1873, so I guess that can't be them then, unless he died and they re-used the name (I've seen examples of this done in other branches of my family). My Michael would've been born 1877. The census for 1911 does say they had 6 children, with 4 living. So that's possible.
I will get onto the Church today and see if they recorded anything.
We'll get to the bottom of this eventually!
I was unable to find Ballingarel on a map, Ballinagard makes more sense. I will mention that town name to my Grandmother and see if it means anything to her but she is unlikely to remember much about this now.
I still have no idea when Michael died, so I can't request a death cert just yet. I've looked through the registers online but none seemed to really fit.
There is a family mystery associated to this Michael, so he may not have been in Claremorris anymore when he died. I will PM you more information about this as it may ring a bell with the person you are seeking further info from.
