yes, the Somervilles / Sommervilles / and a lot more variations are truly an interpreting family. From what little bit I have been able to dug up and from conversations with some family members it does appear that our branch of the family (John) is a younger brother in a large family. I know that the original de Somerville was one of the knights that came over with William the Conqueror. The family then split up with part going to Ireland, Part to Scotland and the rest stayed in England. John and Mary's oldest daughter and her husband and family live for awhile in Westsidewood which is a part of the old Somerville property. I got from a family member that it was because of her family connection they were able to live there. From what I found it would appear that the family had s problem with drinking... the were supposed to have lost the lordship because  of their drinking...
