My daughter is Michelle after my god father michael. I guess find something close & know that is because of him 
Richard in Spanish is Ricardo you can make it feminine and name her Ricarda 
This is what I found: Richard, correctly, only forms two feminine names - Ricarda and Richenda.
Regina? It makes me think of Kings and their Queenly counterparts.
Ricarda and Richenda are the female names for Richard . GOOGLE
Name her Richard but pronounce it like the Cajuns pronounce Richard (Ri-chard)
Do not name her Richard!..a girl called Dick is gonna have a hard time.
Richard, sometimes called Rick. How about Ricky
Call her Richie. Super cute
Named her Ricci instead 
Ricardina I work with a girl who has that name
Ricki or Rikie, spelled different, pronounced the same.
Ricki is cute for a girl.
Richelle, Regina, Richetta come to mind
