From a Late Latin name, a feminine form of the family name Marinus. This was in fact a derivative of Marius, a traditional name of uncertain derivation, but even during the early centuries ad it was widely assumed to be identical with the Latin adjective marinus ‘of the sea’. The early saints of this name are all of very doubtful historical authenticity.
Spanish: 1. nickname from eremita ‘hermit’ (Greek erēmitēs), generally no doubt a nickname for someone living in an isolated spot (compare Hermes). 2. Galician and Spanish: habitational name from any of various places, for example in the provinces of Lugo, Orense, and Pontevedra, named with Old Spanish and Galician hermida ‘hermitage’, ‘shrine’.
