Irish Last Names

Irish Last Names

Irish last names used as first names have eclipsed traditional first names, especially for girls. Irish last names such as Riley, Kennedy, and Finley are more popular baby names in the US today than traditional Irish names such as Bridget and Patrick.

Riley is the top Irish last name used as a first for baby girls in the US today, with Ryan the top Irish surname used as a first name for boys. Along with Riley and Ryan, the other top Irish last names for boys in the US are Connor and Nolan, with the top Irish last names for girls Kennedy and Quinn. Many of these surname-names can be considered gender neutral names.

One fresh factor in Irish last names as first names: Names that start with Mac or O' are now fair game as first names. So if you want to name your baby O'Brien or McNamara, go right ahead. Here's a whole group of rollicking Irish surnames that work for both girls and boys....or you can use one from your own family background.
