I do understand that it can be a bit tough to find information about your family tree, even for those who have always lived on our shores. I'd be happy to see if I can point you in the right direction, towards answers.
The first thing I'd suggest is taking a peek at our Helpful Research Tips
threads. One of our experts put together a very lovely guide about how to search for ancestry information, which might be of some help.
Since you mentioned that your Great-Great Uncle was born in Meath before 1846, contacting their genealogical centre might be a good starting point. You can reach out to the county of Meath for genealogy information by using the email address or phone number provided on their heritage website
, or by contacting the council directly. You might also want to speak to the General Register Office
, or GRO, for records from later in his life.
I wish you the very best of luck on your search! If you need any more advice, please don't hesitate to let me know.
