Jody,Irelands records can be hard to navigate through as spellings of names can vary so much and the further back you go the less records there are.Some of the records that are available online are;
1.1901 and 1911 Irish census
2.Griffiths Valuation 1848-1864(gives names of property owners,townland,parish and county they are in)
3.Tithe Applotment books 1823-1837(gives names of owners of 1 acre or more to determine tithes to be paid to church-not available for all counties)
4.familysearch.org has Irish records for birth and marriage(some)and also civil registration lists(records began being kept for Protestants 1845 and Catholics 1864)
5.www.irishtimes.com/ancestor/ has various very useful pages of info on how to find ancetors.
6.also google whatever county you seek genealogy for as many times obscure listings can come up that could help.(ie.county Louth,Ireland genealogy records)
Sadly,all census records prior to 1901 were either destroyed by government order after the info from them was gathered or by fire in the Public Records Office in 1922.There are a few surviving fragments for a few counties but none for Tipperary or Louth.
The problem I find too with the Irish Family History Foundation(IFHF)is that many times when your looking for a name it doesn't take into account the variety of spellings and other variables.Also,since they've changed over to a buy credits system it could wind up costing a fortune and you may still not get what you are looking for.
Hope this helps.If I can help further,just let me know,Kim
