I have been exploring the various ancestries in my family and all of them can be traced quite far back, except for one. My grandmother's ancestry can be traced no further back than the late 1800s, and her surname only dates back to 1875. In fact, it is impossible for her surname to have been founded any earlier than 1875, because the word itself was not introduced to the dictionary until 1875, and the object my grandmother's surname is named after did not exist before 1875. Obviously my grandmother's family changed their surname sometime in the late 1800s.
I suspect that the reason for the change of surname may be because my grandmother's ancestors on her father's side were not originally British. However I can't be 100% certain that this is the reason. Does anyone know of a valid reason why her ancestors might have changed their family surname towards the end of the 1800's? Was it a common occurrence back then?
The surname in question is "Carbarns".
