Thank you all for your contributions, John Carty appears in the 1901 census for Tullyroe but is gone 1911. He was in Queenstown Cobh with the railway and then on to Limerick. He wife's family, Walsh were a railway family and ran a boarding house near the station. How matches are made. Here is a photo of John. I never knew him as he dies in 1930.
Regards
Tom
