Meaning & origin
Brennon is a modern variant of the Irish surname Brennan, which has been used as a given name since the mid-20th century. It first appeared in U.S. birth records in 1958 and saw a rise in popularity during the 2000s, reaching its peak rank of 5,608 in 2009. Since then, its usage has fallen, aligning with a broader trend away from traditional Irish surname-names. While it has not cracked the top 1,000, Brennon remains a recognizable yet uncommon choice, with roughly 1 in every 106,755 newborns receiving the name in recent years. Its spelling distinguishes it from the more common Brennan, giving it a slightly more modern feel.
Brennon is a variant spelling of Brennan, which derives from the Irish surname Ó Braonáin, meaning 'descendant of Braonán'. The personal name Braonán is a diminutive of braon, often translated as 'sorrow' or 'teardrop', but the exact meaning is uncertain. The surname originated in County Kilkenny and County Offaly, though the given name has spread more widely, especially in the United States.
