Hello

I’m still trying to find out anything about my grandparents, Mrs Helen 'Nelly' Clark, possibly nee Heffernan and Mr Martin Clark (died 1951 at Parkville Drive). They lived at 27 Parkville Drive until Helen's death in around 1977 and before that in Hunthill Road, I think. They had seven children, James, John, Martin, Kathleen, Helen, Margaret, May. I'm guessing they were married around 1915 but having difficulty tracking any records. They were Catholics, so assuming from Ireland at some point? Any pointers appreciated, thank you.
