Thank you so much for looking. The owner of the tree mentioned is based in the US and unfortunately doesn’t know much about the McKenna side who probably stayed in Ireland. I will certainly share any information with you. Do you have a surname project for McKennas?
Do you know if finding the descendants will be possible at the archives? I’m in England and never been to the archives there but may be an option once we can travel again! I am happy to pay for certificates of course but there are so many it would be cheaper (and nicer!) to visit. I guess how useful this depends on whether the records and indexes help me identify the children marriages by their father’s name too.
thanks again, Emma
