Good Morning
Welcome to Ireland Reaching Out and apologies for the delay in replying to your message.
Unfortunately, it may be difficult to find information without a more specific place of origin. Most Irish record sources- church records, land records, census records- are based on specific locations. Until you know a specific location within Ireland, preferably a parish or placename, it may be difficult to do anything more with these records.
Do you have any documentation pertaining to the family that mentions any place names at all? This can include wills, marriage/death records, census records, letters, diary entries etc. Have you tried searching Ancestry.com for any mention of your ancestor?s name in member family trees or messages? Ancestry are also hosting a number of very useful 'webinars' on their site, one on this very subject if you are interested.
Remember to post any new information that you find here. The more information you post, the more likely it is that one of our volunteers will be able to advise or assist you. Also include information concerning which sources you may have already used so others may further your search.
Best of luck with your search
