Me too! I asked my husband (who is very fond of very unique and somewhat distinctive black name, despite his very white skin). He said "Errrmmmm D'James?" Lol
I don't think you need to pigeon hole yourself by picking a "biracial" name. If you want unique, just go with it!
I can give you my husband's list of names, maybe that will inspire you (or terrify you! idk)
Mackrellious
Debarkevious
Octavian
Demetri
Callum
Those are what I remember off the top of my head. I was not, personally, a fan, but they are definitely original!
