"Blend of Aubrey and Anna"
The name Aubreyanna is commonly a female name from the "American" origin.
Aubreyanna is a modern American formation that runs the established given names Aubrey and Anna together into one name. It first appears in United States birth records in 1989, which is consistent with a late twentieth-century coinage rather than a name inherited from an older naming tradition. The name is therefore best described by its two parts, not by a meaning of its own.
The pronunciation of Aubreyanna is aw-bree-AN-uh.
