Hello, I can't say for certain as there are many O'Hare's with the same names. I can only tell you, it is very likely your Michael came from County Down,when we visited the O'Hare name was everywhere. My husbands ggrandfather was a Michael O'Hare born 1833 Lietrim County Down, his Father was Patrick,we can only guess his time of birth. My husbands granddad was born in England in 1880,Michael sen had died 6 mths before Michael jun was born. But as I say if you have any info on your relative, PRONI could help you. Also there is a very good website, Rosdavies northern Ireland, she has done lots of research has lists of nameswhich give some information,well worth you looking at that, Ireland ancestry is very difficult to research but you shouldn't have too much trouble if you are looking at the 1900s. caroleoh.
