NOTES TO DOMESDAY MAP (Compiled by L. F. Salzmann, B.A.) In this Map the manors held by the King, the Bishop and Canons of Hereford, and the two great lay tenants-in-chief, Roger de Laci and Ralf de Mortimer, are distinguished. The castles men- tioned in the Survey are also shown. For convenience of reference the rivers are given, with their modern names, although only the Wye is actually referred to in the Domesday Survey. The county boundary is also shown in its present form. The position of the manors has been fixed, where possible, by the site of the church. The name of a manor or vill is often given in more than one form by Domesday, but only one of these forms can be shown on the Map. No attempt has been made to indicate the hundreds, their boundaries at the time of Domesday being for the most part uncertain.
