I am pretty sure they are his parents, as my brother has also done some research, and has started constructing a family tree. Advice from Ancestry is not to necessarily trust the research of others hence my current research here, rather than relying completely on what my brother has done. I really appreciate your help and will try and access the info you have provided. My Dad was definitely baptised at Cobh so it makes sense his birth cert was there also. I'm actually also interested in looking back further as my brother has done a certain amount of the work. In our family I think there were quite a few Samuel's, Patricks, Williams etc, so likely to be confusing!!
