Did you know all these surnames from Ireland?

If you look, next to each surname in this list you will find a number. That number is the number of people who carry that surname in Ireland. Of course it is the official number given according to the latest statistics made in Ireland, and they take into account not Irishs, but people who currently live in the country. So it is possible that you may find in Ireland a surname that you know perfectly well is not a Irish surname, that may help you get an idea of how many people from the same country from which that surname originates have emigrated to Ireland and have settled there.

Having information about surnames helps us to have information about our history, but also about the history of the different countries. Knowing which surnames are most abundant in Ireland at the moment helps us to take a snapshot of the country's current reality. In this way, and crossing these data we have about the current Irish surnames with the most abundant Irish surnames one hundred or two hundred years ago, we could get an idea of how Irish society has changed and the level of impact that migration may have had in a country like Ireland.

Similarly, it is interesting to try to discover what the current data are on the most used surnames in the countries neighbouring Ireland, and whether they have any surnames in common or if, on the contrary, the coincidences are minimal or non-existent. In this way we can guess what kind of relations Ireland has with its neighboring countries, and whether there has been mobility between the countries or not. As you can see, a few simple statistics on surnames in Ireland can provide much more information than may appear at first glance.
