"Blend of Aubrey and Anna"
The name Aubreanna is commonly a female name from the "American" origin.
Aubreanna is a modern American formation that joins the name Aubrey to the -anna ending seen in Anna, following the same pattern as the spellings Aubrianna and Aubriana. It first appears in United States birth records in 1991, which places it among late twentieth century American coinages rather than among older established names. The element Aubrey is an English surname-name of Germanic origin, and Anna is a long-established given name, but the combined form itself carries no inherited meaning.
The pronunciation of Aubreanna is aw-bree-AN-uh.
