A collection of documents relating to the Channel Islands between the reigns of Edward I and Charles I, but predominantly from the reign of Edward III. Includes the particulars of accounts of royal keepers, receivers and bailiffs of the islands. There are also more detailed documents, such as extents and valuations of particular parishes, inquisitions into the king's properties and rights, military information about garrison wages and military stores, some judicial material, including veredicta and memoranda from the Channel Islands eyes of 1309 and 1323 (E 101/89/1, 3, 6-8). Among the extents, those of Jersey (E 10/189/15) and Guernsey (E 101/89/14) made in 1331, are of particular importance.
