You haven't answered the questions I asked in reply #1 and haven't really given any indication on this thread what you are searching for and what the problem is so it's difficult to help. The Irish Geneaogy site is fairly easy to use (gets much easier with a bit of practice) but there are different ways to search for events.
Mc names, as in many databases, can be troublesome. Here you need to search several ways. Example- surname McSweeney= McSweeney, Mc Sweeney [note space], McSw*n*y [gets variations such as McSwiney, etc.].
If you can't find the people you've looked for there are various possible reasons why you can't find them-
1) event too recent or too old (pre-registration)
2) event not registered
3) persons name not what you are expecting
4) you are searching very restricted date range & district
5) event took place in another area of Ireland or even outside Ireland
