Hi Shane,
I have a little brick wall of my own, My granduncle Charles McCarthy was born c 1862 in Kilbrittain, West Cork, he married Jane O'Regan 1884 Bandon, on his marriage cert it states he was an Excise Officer, Customs & Excise were seperate in those days.
He has children born in Bandon, Fermoy, Stourport in Worcs and Everton Liverpool, I understand there was an Excise training College in Liverpool. One of his sons I am particularly interested in, Denis Finbarr, 1911 English Census states he was born in Fermoy and was a Revenue Clerk. I think there are revenue records in Kew, I wonder are there any online records?
One of my aunts remembers visiting him in North Wales area early 50's , he was married with one daughter who was around 14 years old, she says it was around an hour or hour and a half's drive from Holyhead. I think it may have been as far as Birkenhead, she has a touch of the A's.
I have searched the free BMD english records, a few possibilities but nothing definate.
Brendan
PS. I am also trying to track down Jane O'Regans family, her marriage cert states father Jeremiah, Bootmaker, Bandon
