Hi Fiona,
I know you have replied to my own post from a few years ago, but I have just found this post of yours after someone else replied to my post today, and feel like they are connected to you with Cornelius.
My great, great grandfather was named Laurence Ryan and they migrated to South Australia in 1876 where they had their last child - my great grandmother named Emma Ryan (but had several other children in Ireland before leaving) .
When I visted Ireland in 2019 I was taken to Carhue House by a local who was renting it from a Ryan who owned it but lived in Dublin at the time, and I spoke to him on the phone while I was there who said his father or grandfather was named Laurence. His name was Neil Ryan. I have pictures of Carhue House if you would like them??
I do believe that Cornelius and my great, great, great grandfather were brothers and have a theory that his name may be John, who then had my great, great grandfather named Laurence. Do you have any info to confirm that Cornelius had a brother named John?
I really feel like we are connected with these Ryan's in this tiny townland of Carhue, so hoping we can connect our info somehow!
Crossing everything,
Rachael in Adelaide, South Australia
