Yes I've looked been in touch with the sacristans at the Church of the immaculate conception, they did find my Grandfathers birth etc. initially but when I asked them to look for the rest of the siblings, they said they couldn't find anything, I suspect they probably didn't really look as I had to contact them numerous times over a year. I have searched the newspaper archives but no luck, unfortunately when I contacted the archives for the newspapers, they said I would need more information than I had and would be better visiting, however that is not an option imminently. I had not thought of looking into the schools though, I'll follow that up.
Many thanks.
