What is the sources of the names you list?
Do you check Griffiths Valuation?
How about did you check Tithe applotments?
Finally, checking for Descendants in the same area in 1901 or 1911 Census would be useful, No?
Many surnames have dozens of different lines or families -
It is a giant leap to assume because the place and surname are similar or the same that it is "your" line - ordering BMD (*Birth/Baptismal-Marriage-Death) Certificates (at 20 some euro each_ to determine it is your ancestors -- or the wrong line/family and more to the next --- keep in mind running down the wrong "Line or family" wastes time and effort for someone who is not even related to you.
Exp. researchers make the assumption is is NOT your family until is it firmly proven by a long line of documentation (BMD Certs) that you decend from them.....do not jump to conclusions without definitive proof.
Just trying to help you not make mistake first timers do, work from what you know FOR SURE (liek Grandparents, Grt GP) and work backwards from Census, Griffiths, Tithe - must know Townland where they lived as it is critical....
