Fabulous Book about the Darleys

I have discovered a fabulous book called _Your Darley Ancestors_.It was written by Lon J. Darley, and published by Gateway Press of Baltimore in 1979.In it, the author traces his lineage back to Sir Edmund Darley of France circa 1034.He also mentions a book called _William Frederick Darley and Jemima Brown Thurkell and their Descendants_.
