I have information >from a local Book of Residents implying a surname
change around the early 1800's. The name appears in the shape of "Name
X vel Name Y". I know it was a time when many changed their names in
the transition >from patronymic names. My question is whether such name
changes were registered anywhere? Or a person could be registered once
in his old name and next time with a new name? How about later years
(such as the end of the 19th century or the early 20th)?
