"Variant of Davion"
The name Davionna is commonly a female name from the "American" origin.
Davionna is a modern American feminine formation built on Davion, a name that appears in United States birth records from the twentieth century, with a feminine -a ending added to the stem. The same shape appears in forms such as Davonna. No meaning from an older language is documented for it, and it is best described as a twentieth-century American creation rather than a name carried over from an established naming tradition.
Davion means "Variant of David 'beloved.'.".
The pronunciation of Davionna is day-vee-AH-nuh.
