Hi C.
Thanks for the info, but as we only have their names (common Irish ones!) and approx year of birth based on 1841 and 1851 census, I think it's a hopeless task really. I suppose if I ever found a baptism for my husband's 2 x g.grandfather around 1824 in Dublin that might be a start.
Anyway, I'll dip out now, the topic is about Irish families living in Manchester, although my husband's 2 x g.grandfather and his Liverpudlian and probably English wife did move to Manchester in 1851 and then they vanished.
