I count at least five priests with the same surname in one parish over the course of less than a hundred years (taking some at the beginning of the period when they were elderly) during the 1700s.
It's rather puzzling to me, since I don't consider it a place where the name was frequent. That is, the parish. (Though of course that is difficult to tell in the 1700s)
Somehow, it doesn't seem random.
They clearly had some sort of regard for each other. The second man mentions the first in his will and they were both high officers - a bishop and a vicar.
The first and fourth are buried in the same grave.
The third and fourth were said to be brothers, with the one succeeding the other.
The third was buried in another parish, but with the stone erected by the fifth, who gave his address on the stone.
And there are some other circumstantial things that may connect.
The first took charge of the parish in 1657. Seemingly the same year a vicar of the diocese with the name was elevated to run the archdiocese of Dublin. I have wondered if he could have been replacing the vicar (whose parish I am uncertain of). I know that he himself was a vicar 15 years later, but I am not sure when he became one. Potentially, it could be the same year he took charge of the parish, as he was about 30, and probably had the education for it.
I believe the bishop was ordained as a young man seemingly very close to the borders of the current parish, but not inside it. However, I think it is possible it was inside it back then.
I strongly suspect that they had some sort of special local support.
Perhaps, it was clan-based rather than narrowly familial. But I wonder if it could have been a certain branch of the clan, rather than anyone with the name.
I believe the last chief's wife held land locally. The bishop was her chaplain, after her husband died. Perhaps, before? I wish I knew exactly where she lived, when not in Dublin and when exactly they got married.
Also, I wish I could figure out how the men were related to each other, but it seems probably impossible. Or at least would require rare documents, if they survive somewhere in Europe. (Some ordination records did give the parents names).
