Edith Latimer can trace her ancestry to several Barons and Lords, including Wido de Reinbudcourt (born about 1040 AD), who was a Doomsday governor under William the Conqueror. While Henry Samson's lines do not connect to any known royalty, there are many Lords, Sheriffs, Governors, and Barons.
For much more detailed information on the Samson ancestry, see the following series of articles written by Robert Leigh Ward in The American Genealogist, 52:198-209 and 56:141-143, and The Genealogist, 6:166-186.
