They became one of the most powerful Gaelic families in Leinster, famously led by figures like Fiach MacHugh O’Byrne during the Elizabethan era. The transition from surname to given name occurred primarily in the 20th century, particularly among Irish diaspora communities. Today, it represents a meaningful way to honor Irish heritage while choosing a distinctive, strong-sounding name.
