So I've got a relation that was born 8th February 1917 Tuam, Galway, Ireland. Now at that time Ireland was under British rule but shortly afterwards gained independence (that's my understanding anyway).
So I'm trying to trace the birth certificate and I'm wondering about open questions such as: was she 'British' or 'Irish' or did she start 'British' and become 'Irish' automatically as a child?
And more to the point - where am I likely to find her birth certificate? Would that sort of thing have been centrally held at the time?
