A short, breezy name with a sophisticated yet upbeat image, that doesn't betray its Irish roots.
Bree first came to notice here in 1971 via the complex prostitute character in the movie Klute, which earned Jane Fonda an Oscar. More recently, it was tied to the character of Bree Van de Kamp on Desperate Housewives.
Other recent references include Stephenie Meyer's novella The Short Second Life of Bree Turner in the Twilight series. And in the popular Fancy Nancy children's book series, Bree is Nancy's bff.
The Bree spelling is much preferable to the cheese-related Brie.
