PJ, With respect, I think you need to try a bit more research and then post what you know, and be specific with your request. I probably split the families into two requests, one for John Hayes and one for Martin Hayes. List all the names and ages from 1901 and 1911 census. Try and find the marriages of John and Martin. 1911 will tell you years married and number of children. Look on Family Search civil registrations around that time. You'll get a quarterly date and location for the males, then you should use data to search for spouses with that exact date and location. You might also look for subsequent BDM events like deaths or marriages of all their children. That should bring you closer to current living generations. One of the problems is that you are looking for people who precede living memories. I'd then look for submitted trees or you may even be able to search local Irish phone books. Peter
