OK a bit of an update.
I went to the land registry in Dublin whilst in Ireland in June/July. I found my John Driscoll living on land that I believe is the mill land with Rev Townsend the lessor. There were a few houses under the one title. I shall try to attach.
I asked around the local people and was told the Driscoll who was living there in the early 1900's went by the nickname Bawn. His name was John and he lived with his sister Ellen - the children of Jeremiah Driscoll and Bridget McDonnell (daughter of Jeremiah McDonnell - butcher). John was a pensioner from the Coastguard. Both John and Ellen are buried in Clonakilty's famine graveyard (during the 1940's).
The house was on the main road near the mill an just across from a historic water pump. It is now a pile of stones next to a couple of houses that are up for sale. Apparently there was a shop nearby and I believe my O'Neal GG Grandmother was from the family that ran this.
I am curious if anyone can tell me about the nickname Bawn, and also the name Blackstaff as I believe there were Driscoll's and Fitzgeralds that went under this name?
It would seem that a number of youngish men from this area ended up in London around the 1860's but there must have been earlier migrations as the Irish families seem to have connections already in the dock area.
I would very much like to find out anything I can about my family. I wonder if the Driscoll's from Carrigtishane and Currabeg are related?
