From Greek
φιλος (philos) "friend, lover" and
μενος (menos) "mind, purpose, strength, courage". This was the name of an obscure early saint and martyr. The name came to public attention in the 19th century after a tomb seemingly marked with the name
Filumena was found in Rome, supposedly belonging to another martyr named Philomena. This may have in fact been a representation of the Greek word
φιλομηνη (philomene) meaning "loved".
