In researching my mother-in-law's family, Albin, I came across the List of Barons Present at the Signing of the Magna Cara in 1215 and the first one listed is William d'Albini, Lord of Belvoir Castle. Also listed is Odonel d'Albini, (Alban), Philip, William, Jr.Oliver de'Albini, another Philip, and William D'Albini According to the information in this file, these names became Dawbeny, Daubeny, Alban, and Albin. The list also mentions the book "The Magna Charta Sureties, ans some of their descendants who settled in America", by Frederick Lewis Weis and Arthur Adams. Have no connection with either writer. Just for information.
