The name Francisca was given to 42 girls born in the US in 2015.
This name is also used in The Netherlands, where it is a firm top 1000 name (for all ages). It was used most often between 1945 and 1968 (with 522 births in 1946 being the highest number), after which the name slowly declined in popularity. There were only 7 Franciscas born in 2011.The Dutch pronunciation of this name is: frahn-SIS-kah.
