Term: Morisca

Hello, is anyone familiar with the term "Morisca'? I believe it appears after the daughter and mother's name on Pasquela Prudencia's 1749 San Luis Potosi birth record on the link listed below. I first thought it was their middle name.

I googled the term and it means Spanish Muslim.

Thank you,

Cynthia
