Joe McKelvey, executed in Dublin (by Free State), 8th Dec, 1922
I think the other name must refer to Sean McCaughey who died on hunger strike 11th May 1946 in Porlaoise.

The other two names don't ring any bells but "Dougherty" (if he's from the nrth) is more likely to be "Doherty". I occasionally run into MacAreavey and the next time I do I'll try to get more information from him.
