Happy April, and don't forget to consider it as a baby name! April is Latin, meaning "to open," and wasn't used as a given named until the 20th century. It could have been inspired by usage of the French name Avril, a variant of the Old English name Averil, meaning "boar battle." Originally, April came from the Latin word for "second," because at first it was the second month in the year. April symbolizes spring and the freshness and florals that mark this time.
This was very popular since about the 70s, and is still slowly decreasing in popularity. In 2010 there were 832 baby girls named April, ranking #378, and in 2011 it was #395. Be sure to get creative with nicknames for April, as the unwanted choice is "ape." Perhaps Rilla? Prilly?
April's birthstone is the diamond, and while Diamond is used as a baby name, more adventurous namers might like to go with Diamanta or Diamanda, which are international and mean "diamond." Keep in mind Diamante is usually a surname.
