I would love to collaborate with you! I just signed up with this forum today so I apologize I've no idea how to share information just yet, if I did I'd shoot you my email address. Things get confusing becasue there are so many John Eaton's, but my grandfather, who was written down as an Alexander John Eaton or "Alexis J W Eaton" in early census reports, is actually the John Wallace Eaton who, among other things, was a professor of German at the University of Michigan, which is where he and my uncle died in 1948. He and his younger siblings were all born in Lancashire area, whereas the older 3 (2 died as infants and are buried with my great grandparents in Deansgrange cemetery, & 1 named Anna two years older than my great grandfather who moved with them to Lancashire) were born in Dublin. I've also obtained a record that I _think_ may be the marriage of our (yay! so happy to have found you!!) great grandparents' marriage in 1883 in Dublin. By the way, I'm not sure why my original post labeled me as John, my apologies for the confusion, but my name is Samantha & it's a pleasure to meet you & muse over these mysteries with you, Roger!
