Brennae is of Irish origin, meaning 'beautiful'. It's a modern variant of the traditional Irish name Brónach, which itself comes from the Irish word 'bron' meaning 'sorrow'. Brennae gained popularity in the late 20th century and has since been used as both a given name and a surname. Notable individuals with this name include American soccer player Brenna McNally and Australian actress Brenna Harding.
"Brennae saw its debut in 2001 with six newborns, but unfortunately, it didn't gain further traction as no other births were recorded after that year."
