Hi,
Thank you for your replies.
Yes, Kingskerswell, in the 1911 census, that is the family I'm looking for: Hugh F. HENRY and his wife Gertrude. After the children left home, Hugh and Gertrude moved to Newcastle.
Yes, Glen-Ada may be the name of a house as you suggested, Aghadowey. Any suggestions on how to find what the street address is? Or is a 1920s (specifically 1927) city directory the best way?
