Jo, The first complete census records for Ireland are from 1901. All earlier ones were destroyed, except for a few fragments. Registration of births in Ireland began in 1864, so you should be able to find these for the children. The LDS library has filmed these records. Go to www familysearch.org to search the LDS catalog. Enter "Ireland" under place, then select "Ireland--Civil Registration--Indexes." You can then order the film to be sent to the LDS Library for about $5.00. Mary Kay
