I think your Timothy would actually be the one that poster Patrick Keefe referred to, as he also mentioned Bedwellty, and it seems that one is a bit younger than the one I have, but just in case. . .
I have a Timothy Keeffe baptized in 1857 in Ballyhooly, son of my ancestors Arthur and Margaret (Harrington). This is probably a bit of a long shot, since there was a death of a 10 yr. old Timothy dying in the area in 1867 which I suspect was him.
I also suspect that Timothy's grandfather was named Timothy Keeffe.
I'm just trying to determine what happened to Arthur and Margaret's children, as I've only been able to trace 3 of their sons that went to the USA.
