P. W. (Patrick Weston) Joyce translation
] Crossans: travelling gleemen: the clothes, musical instruments, &c., were the property of the company. This word is the origin of the Scotch and Irish family name MacCrossan, now often changed to Crosbie. A company of crossans had always among them a fuirseoir, i.e. a juggler or buffoon.
