Henry III of England, by grant of 26 September 1234, conceded a market at Buttevant to David Og de Barry to be held on Sundays, and a fair on the vigil and day of St. Luke the Evangelist (17 October and 18 October), and on six subsequent days. This was done to further the economic prosperity of the borough and connected with a widespread network of such markets and fairs which indicate "an extensive network of commercial traffic and an important part of the infrastructure of the growing agrarian and mercantile economy". The most important markets and all fairs were associated with the major boroughs and can be used as a gauge of their economic and social significance as also the 1301 quo warranto proceedings in Cork at which John de Barry "claimed the basic baronial jurisdiction of gallows, infangetheof, "vetitia namia" and fines for shedding blood (where 'Englishmen' were involved) in his manors of Buttevant, Castlelyons, Rathbarry and Lislee".
