Well I have John Shevlane and Bridget Murphy as ancestors, and I also have a list of their children - Anne, Patrick, John, Bridget, Bridget (2), Sabina, Mary, Kate, Michael, Michael (2) and Martin. Big family indeed, I've located everyone except Anne, the elder Bridget, the younger Michael and Martin. Martin is known to the older generation of the family still living, but they only vaguely know he "died young". Anne wasn't known about, so she likely died in infancy. Same might be assumed for elder Bridget, since the younger was likely named after her. Younger Michael is completely unknown to memory again suggesting premature death. All this being said, I know there was heavy involvement with the Civil War at the time. I am told one of their aunts was murdered and events like that may not appear on official records.
Coming to my point, there is no family I can find matching these names. Perhaps there was some spelling variety making them hard to locate on census? In any case, census from 1901 won't help me very much in finding further ancestry.
John Shevlane does seem to have been born 1st July 1867, since this is only record in region matching his rough age and name. If so, his parents are John Shevlane and Biddy Mills. I note they also have son Richard "Dick" Shevlane (1865) who may have died in 1949. Plus a son James, and daughters Bridget and Mary. The name Richard struck me as unusual and I see this older Richard, old enough to be brother of this elder John Shevlane.
I know also about the Cuffe cousins, and their connection to us via Catherine Shevlane daughter of Michael Shevlane. Looking at dates, I am assuming Michael to be another brother of John and Richard potentially. It's all very complicated. How Edward "Ned" Shevlane, Manus Shevlane, and Bryan Shevlane may relate remains completely unknown - though I bet they do!
