Many of the originally Barbarian names in history were Christianized. Many Christian saints with Slavic/Germanic names were given similar-sounding Greek and Latin names. In this way "Kuzma" (blacksmith) became "Cosmas", "Mariam" became "Maria", a feminine form of the old Roman name Marius.
Was there a Greek or Roman name Jesus so that "Yehoshuah" was named Jesus in translation?
I found that e̯esus meant "good" in PIE.
