Tara,
many sincere thanks for your help. Yes, I did appreciate the help and advice offered by Shane Wilson & Burgess Donnelly on Ancestry and purchased a subscription to Rootsireland.ie. I got a bit further yesterday but am still bit confused. I believe there were 2 Edward Byrnes, one born 1805 married to a Catherine Kelly and his son born 1841, possibly the son that married Emma Lovell. I am just about to trawl through your findings to see if they tie up.
