Maps are based on data from the 1901 and 1911 censuses of Ireland. Not all surnames are covered at the moment since it takes time to generate the maps. If you would like to see a surname added, please message me here on Facebook.
Surnames are case sensitive, for example, McGee, Mc Gee, Mcgee and Magee all have their own maps. Please keep this in mind when searching.
Since I have put a lot of work into developing these maps, I would be very grateful to anyone who might share this website with friends and family.
