The word baron comes from the Old French baron, from a Late Latin baro "man; servant, soldier, mercenary" (so used in Salic Law; Alemannic Law has barus in the same sense). Isidore in the 7th century thought the word was from Greek βαρύς "heavy" (because of the "heavy work" done by mercenaries), but the word is presumably of Old Frankish origin, cognate with Old English beorn meaning "warrior, nobleman"). Cornutus in the first century already reports a word barones which he took to be of Gaulish origin. He glosses it as meaning servos militum and explains it as meaning "stupid", by reference to classical Latin bāro "simpleton, dunce";[2] because of this early reference, the word has also been suggested to derive from an otherwise unknown Celtic *bar, but OED takes this to be "a figment".[3]

There are two types of Baronies within the Principality of Lyonesse and those are, Hereditary and Court Baronies.  Court Baronies hold title to no lands and are an honorary Title for the life of that particular Lord or Lady. Hereditary Baronies are inherited as specified by the Title holder, some are traditional (i.e. father to son), some are matriarchal, and some are handed down to the most qualified heir in that Baron/Baroness' eyes. All Hereditary Baronial Ascensions are approved by the Armorial Court.
