Unfortunately, colonial denization and naturalization records can be difficult to find, since their location varies from one colony to another. They may be found at the local jurisdictional level as well as the colonial level, in court minutes, government records, deed books, legislative journals, statutes, private papers of proprietors such as William Penn, and land patents. Now, however, Lloyd Bockstruck has compiled this comprehensive register of British denization and naturalization records between 1607 and 1775 from a large body of published literature, then expanded and improved on the information by examining original source material not previously available to scholars. For the more than 13,000 persons listed in this invaluable work, some or all of the following information is given: place and date of naturalization or denization; names of spouse and children, as well as where or when they were naturalized or endenized; country of origin; religion; length of time in the colony; location of current residence; occupation; and any alternate names found in the records.
