Thanks, I just wanted to check it was ok to ask for this type of info first.
It was 23 Newry Street, Holyhead. My grandmother was born and lived in Birkenhead then Liverpool, but her parents were born in Holyhead originally and she married in the Tabor Chapel, Valley, so I assume the occupants would have been family, details of which would help my research! The marriage was 1925.
Thank you.
