According to Warren and Palmer, the name "Com" (Ether 10:32) has a parallel in Maya. It means log stool or armadillo (Laughlin: 1975 Tzotzil dictionary p. 104). [Bruce W. Warren and David A. Palmer, The Jaredite Saga, p. 8-20]
It is interesting that Com2 was the son of Coriantum2 (Ether 10:31), just as Com1 was the son of Coriantum1 (Ether 9:24-25). Could this be a case of name adoption by kings? [Alan C. Miner, Personal Notes]
