This book is a compilation of the work of Richard Timbrook Wilson (1920) and Richard John Franz (beginning in 1957). The compilation was published by Marguerite S. Roll in 1992. The book includes bibliographical references.

Under copyright laws that were in effect before 1978, a work that was published without copyright notice fell into the public domain. If the work did not include the word “Copyright” or a © (a “c” in a circle) and the name of the copyright owner, the work would enter the public domain.

"The Genealogy of the Roll Family" was distributed in fixed form before 1978, and without the required copyright notice. It contains 514 pages. Pages 124-126 constitute Mrs. Roll's addition, which is merely a list of names, dates, and places. Therefore, the whole book is in the public domain.
