Origin: Irish

Meaning: Descendant of Díomasach; Proud

Once exclusively a surname, Dempsey is once again rising in the ranks as a given name for bouncing baby boys. It's blessed with Irish roots and derived from Ó Díomasaigh, meaning "descendant of Díomasach." It's alternate meaning of "proud" is inspired by the O'Dempsey clan, who defended their land in what is now counties Laois and Offaly for over 300 years. You may also recall the dreamy American actor Patrick Dempsey of Grey's Anatomy and the films Enchanted, Loverboy, and Bridget Jones's Baby.
