Thanks for the replies, all!
Horsley, that explanation roughly fits with what I thought - although my reading had it going the other direction, with Stafford continuing James' interest. Not particularly surprised that I'm wrong on that one!
Josey, that is indeed the family I'm thinking of. This James and Stafford were the sons of another Stafford O'Neil who died in 1894.
However, doing a little bit of digging based on Horsely's probate suggestion means that I
might have cracked it. This notice can't have been probate for the Stafford O'Neill in Rocktown, as I know he didn't die until 1945.
However, there is another Stafford O'Neill of Ballymacpeake (I suspect a relation between the two, but can't prove it). This other Stafford O'Neill (actually christened George Stafford) had emigrated to New Zealand in 1884 and died there in 1932. That would potentially line up with the above notice being for probate.
This Stafford also had an elder brother called James, who of all their siblings was the only son to remain in Ireland. Was James looking after some land for his brother Stafford?
My only confusion is that as far as I'm aware the Ballymacpeake Stafford-O'Neills had no land interest in Dreenan. Stafford's will in the New Zealand Probate records apparently shows the following legacies (I'm going by someone else's transcription, I have no access to the original image):
- £20 to daughter Cecelia McErlane;
- Debt from mortgage to son Pat to be split two-thirds to daughter Nellie and one-third to son Jack;
- Remainder to sons Stafford and Pat in equal shares;
- Stafford and Pat to pay their mother Bridget £100 per annum.
As far as I can see, no mention of any land in Dreenan - unless Stafford already considered it as 'belonging' to James, in his absence?
