Hi Ger,
Thanks for the info.
My interest in Nagle is a bit earlier than the records that you found however It's great because this opens up a another new line that I was unaware of.
The Nagle that I knew about was Ellen Nagle (1854-1919) who married Michael Winkle son of William and Margaret. Now Ellen was born in Shoreditch, London to Richard Nagle and Ann (surname unknown) who were both born in Co Cork around 1820. I believe Ann was from Kanturk but I know little else. I'm not sure where or when they married but I assume it was in the 1840's and probably in Ireland.
I've now got two places to visit when I come over next April (Castlemagner and Dromtarriff)
Thanks again for your help
Dennis
