Surnames as a Science (1884) - Robert Ferguson - Bog

That portion of our surnames which dates back to Anglo-Saxon times, and so forms a part of the general system by which Teutonic names are governed, is distinctly a branch of a science, and such as has been treated by the Germans, upon whose lines Ferguson generally followed. It is part of the author's object to show that this portion of our surnames is a very much larger one than has been generally supposed, and that it includes a very great number of names which have been otherwise accounted for, as well as of course a great number for which no explanation has been forthcoming.
