The Drane name seems to originate with the Scots when it was MacTrean which came from "Wren" as in the small bird held sacred in some beliefs. The Dranes were the Champions of the Scottish kings, meaning that if the king were challenged by someone throwing down a gaunlet, the champion would pick-up the gaunlet and defend the king's honor.
The coat of arms refered to would be read: Arms: Argent, a lion rampant proper, in chief three mullets gules. Crest: A demi-lion rampant proper.
"Argent" indicates that the arms, or shield, is silver. "A lion rampant proper" indicates that the lion is standing on its hind legs in the center of the shield. "In chief" indicates the upper 1/3 of the shield. "Three mullets" denotes honor and achievement in service to the state. "Gules" indicates that the mullets (which are stars) are red. The silver of the arms represent serenity and nobility, which the red represents fortitude and creative power.
