The name Inez was given to 61 girls born in the US in 2015.
The Spanish form of Agnes is Inés, not Inez. Inez seems to be an adapted foreign version. In Spain this name is very rare. According to the Instituto Nacional de Estatística, 31 women in Spain are named Inez, 25 of whom are foreigners, mostly from Brazil and Poland.
