this is to give you an idea of where the father's were living during the 1848-1864 time period and where in the parish registers for county Calow and co Wexford to look for the births of the people you seek. You can go to your nearest LDS(Latter Day Saints) library and view the county Carlow parish registers as they have them all on microfilm.Hope this helps,Kim
