"Blend of Frances and -ella"
The name Francella is commonly a female name.
Francella is built from the name stem Franc-, as in Frances and the Italian short form Franca, plus the feminine ending -ella, a diminutive suffix that appears in Italian and Spanish names such as Antonella, Mariella and Rosella. The name appears in United States birth records from 1918 onward. That describes the parts the name is made of; no separate meaning is recorded for it.
The pronunciation of Francella is fran-SELL-uh.
