Hi markamurff. Welcome to Rootschat.

I have moved your query to the main Armed Forces Board.
Going back to your original question... St Kevin's could be where he was born, or baptised, or even just where he grew up. It would be where he
believed he was born and what he told the recruitment officer.
I will leave this in Armed Forces for now in case you have any further Army questions about him - but as aghadowey points out - you may be better asking people on the Dublin board for help.
Also follow up aghadowey's baptism suggestions.
Do let us know if you make any progress.
Milly
