Finlays do seem a bit thin on the ground in the area.
As for religion, I'm not sure, but I don't think any were Catholic at any time.
As I said earlier, I need to have a good chat with my cousin to find out where he got his info from. The William baptism with Sarah Hunter as the Mother looks very promising, although the Father as a Policeman is news. But, if he was a Corporal in the Army, then maybe going on to be a Policeman may not be too much of a stretch.
Thanks, Eric.
