The unisex name Aubrey is scooting up the girls' popularity charts, along with the revived Audrey; it has been in the Top 50 for the past four years, and is now at Number 18. After being a 100% male name, it tipped to female in 1974, and is now 98% girls.
Aubrey was a relatively popular male name in England in the Middle Ages, then fell from favor. One possible factor in its popularity for girls is the song about a girl named Aubrey by the group Bread in the 1970s. Most prominent bearer now is deadpan comic actress Aubrey Plaza, breakout star of Parks & Recreation. Terrence Howard is the father of a grown daughter named Aubrey.
