Gervasius

Possibly a Latinized form of a Germanic name with a first element deriving from ger "spear". The second element is uncertain, though some propose it to be Gaulish *wassos "servant". Alternatively the name could be related to the Greek word γεραιός (geraios) "old".

Saint Gervasius was an early martyr from Milan whose remains (along with those of Protasius) were discovered in the 4th century by Saint Ambrose. He was thought to have lived a century or two earlier.
