Hi all!
My best friend's surname is Bertholet. She lives in the French speaking part of Switzerland. Although the most Bertholets originate from France, my friend says that her family comes from Prussia, and that she might be a descendant of a certain Queen called Berthe ('la reine Berthe'). I don't know if it's really true what my friend says, but anyway, we'd both like to hear what the meaning is of her surname.
Thank you in advance!
Lucille
