Thank you for writing on the Community Forum! 😄
First of all, there are some resources on the Tourism Ireland website
that may be of help.
The best start is with a good paper trail of birth, marriage, and death certificates back as far as possible. 📜
Before 1864 records were kept in the form of church and parish records; while some of these have regrettably been lost over the years, all the surviving records have been sorted into county based genealogical centers
In 1864 civil registration was introduced in Ireland, which is when we started seeing the formal registration of births, marriages, adoptions and deaths. These records have been kept at the General Register Office of Ireland
(GRO), through the Irish Genealogy website, to this day.The Surname Website
by John Grenham could possibly help you find some more information and Find My Past
has a lovely website that may be of help too.
I hope this information will be helpful!
Have a great day. ☘️
