Presumably from Proto-Italic *yemanos, from Proto-Indo-European *yemH- (“twin”), in view of Proto-Celtic *yemonos (Old Irish emon (“twin”)). If this is true, the g- must have been analogically introduced from gignō (“to give birth to”), genus (“offspring”).

Geminus of Rhodes (Greek: Γεμῖνος ὁ Ῥόδιος), was a Greek astronomer and mathematician, who flourished in the 1st century BC. An astronomy work of his, the Introduction to the Phenomena, still survives; it was intended as an introductory astronomy book for students. He also wrote a work on mathematics, of which only fragments quoted by later authors survive.
