Bertolin

The Bertolin surname likely originated in the Alpine region, most probably in Northern Italy. It may be a patronymic derived from medieval first names such as Bertold, Berthold or Bertholin. The prefix "Bert" could stem from the Lombard word "''berht''", meaning bright or illustrious.

A commemorative monument known as the Waldensian Stone was erected north of Le Bourcet (now part of Althengstett) to honor the town's original settler families, including those with the Bertolin surname. Le Bourcet was named after the Italian village of Bourcet in the Cottian Alps, from which the majority of the settlers originated. This connection suggests that the Bertolin surname may have a more specific origin linked to Bourcet. Provided by Wikipedia
