“In former times, many persons holding certain feudal rights from the Crown were called barons, but in the strict legal sense, the title was only due to him whose lands had been erected or confirmed by the king in liberam baroniam. The advantages conferred by the right of barony were considerable. Such a right conferred on the baron both civil and criminal jurisdiction within his barony; and under the clause of union contained in his charter, he was enabled to take infeftment in the whole lands and rights of the barony in, what was at that time, an easy and inexpensive mode.” John Trayner, Trayner’s Latin Maxims 264 (4th ed. 1894).
