Meaning & History
Some derive this name from the French word "gui," meaning mistletoe. Others think it comes through the Celtic name "Kei," from Caius. Others belive the name comes from the French words "guide," a leader, or "guidon," a banner. The name may come from "Guillaume" (William), from which have also come the French names Guyot and Guion.
