"Variant of Davion"
The name Davione is commonly a unisex name from the "American" origin.
Davione first appears in United States birth records in 1987 and is best explained as a spelling variant of Davion, with a final e added to the ending. Davion is itself a modern American coinage rather than a name carried over from an older language tradition, and no meaning is documented for either form.
Davion means "Variant of David 'beloved.'.".
The pronunciation of Davione is DAY-vee-ohn.
