Popular Irish Surnames, Their Origin and Coat of Arms

Hi everyone. I hope you all had a good week. So what’s in an Irish surname? Well, here at The Irish Store our best selling personalized Irish gift is our Personalized Framed Family Crest with the vast majority of these gifts being delivered to our American cousins. This is no surprise. Some 33 million Americans claim Irish heritage. It is estimated that almost 5 million have emigrated to the US since the 1700s. Of course, the mass exodus of Irish to the States took place during the Great Hunger in the years between 1845 and 1852. The population of Ireland declined by 25% and to this day the population is still substantially smaller compared to what it was in the 1800s. Here are some of the most popular Irish surnames.

The Murphy clan originally had a large stronghold in the province of Leinster. Today, the name is found in all parts of the country with the largest percentage of Murphys residing in Munster.
