“Gershon” means exile

Gershon: The eldest of the three sons of Levi, born before the descent of Jacob's family into Egypt. (Genesis 46:11; Exodus 6:16) (B.C. before 1706.) But, though the eldest born, the families of Gershon were outstripped in fame by their younger brethren of Kohath, from whom sprang Moses and the priestly line of Aaron.
