Just for fun I decided to use it to search for my great-grandmother. I already have lots of information about her and her family. I answered all questions truthfully but the results weren't accurate (some statements very misleading which could easily confuse beginners).
1) gave 3 versions of her surname- but didn't include one her family used
2) "The good news is that full pdf images of all registered births 1864 - 1915, marriages 1882 - 1940 and deaths 1891 - 1965 are freely available at IrishGenealogy." All not yet online
3) "The relevant Presbyterian records are divided between the following parishes: Aghadowey Ballylintagh Killaig Ringsend" Aghadowey is the parish. List doesn't include neighbouring churches. She wasn't actually Presbyterian but that was closest I could get from the choices
Did another search and found list of occupations very limited.
To be used with caution!
