Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Many Of the authorities cited are not men tioned in the text, as it would require much space to enumerate all who are entitled to notice, but they are all standard or authentic writers. One of the most important sources has been the printed edition of the records of the wills and deeds Of the county of York, to which I had access through the kindness Of W. S. Mathews, Esq of Berwick.
