Brendan, I don't know if we have a link but it looks promising. I am searching for my g.g.g.grandfather Morgan Sweeney who was married to a Johanna Donahue. The only link I have been able to find on the internet resources is a Morgan Sweeney with a daughter Johanna Sweeney who married Charles Gaiter. It is interesting to note that your Charles & Johanna have a son Morgan. Johanna might be a sister to my g.g.grandfather Patrick Sweeney b. 1829 who came to Connecticut in 1880. He lived in Cahirciveen, County Kerry, Ireland just before coming to the USA. Please let me know if you have anything to add. Thank you.
