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.
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.
To search the actual census data use to produce these maps, please visit: The National Archives.
I’m also considering whether to create a dna map for each surname. My idea is to place dna markers on the map based on geographic information people have about where their ancestor came from. This would help in terms of establishing various dna clusters for a given surname. If you think this would be useful and have any advice to offer me, please send me a message here on Facebook. Thank you!
