Okay, this is something that happens in genealogical research too….
It seems there’s some doubt as to the real name of Fr. Daniel O’Brien (so listed by Moran and his sources). The cause for Richard Creagh and 41 Companion Martyrs of Ireland lists his name as Donal Breen!
Okay, I can buy Donal as being the guy’s Gaelic name, with “Daniel” being either his name in religion or the functional equivalent of Donal that he was baptized with. But. Usually Irish authors are pretty clear about whether a man’s an O’Brien, Byrne, or Breen, even if folks from other countries are easily confused. So what was the real surname of Fr. Daniel?
The cause for sainthood seems to be a little stalled. They haven’t even named them official martyrs yet. Bah.
