dana
Etymology
IrishEnglish
The surname Dana has several possible origins. It may come from the Irish surname Ó Dána, meaning 'descendant of Dána', where Dána was a personal name possibly meaning 'bold' or 'daring'. In some cases it arrived in America with English settlers of Norman descent. The three notable American figures bearing this name — all active in the 19th century — are unrelated to each other by blood but are grouped together in biographical references because of their shared surname and historical prominence.
