“The term Border Reivers describes a number of English and Scottish families who fought a seemingly endless series of bloody confrontations from the 13th Century to the mid 17th Century. Sheep stealing and burning each other’s homes were part of everyday Border Reiver life – they were rugged, tough people who lived by their own laws.â€
The researchers theorize that males may have adopted the Robson surname in an act of subservience to this powerful family. As always, however, there could have been non-parental events such as adoption and illegitimacy. For more information on this topic than you could ever need, see the Border Reivers DNA Project Website.
Ah, a genetics question close to my heart 🙂
Another, probably more modern phenomenon, is the mutation of surnames. There was a Robinson family where I grew up who had apparently once sported a much finer surname, but somewhere along the line grew tired of evicting the extra n and simply allowed the mutated form to go to fixation.
