As can be seen, BASTINs in Belgium are fairly numerous. Many of them live in, or around, Charleroi, Belgium, which is believed by some to be the ancestral home of the surname.
According to some sources, BASTIN is a very old surname with roots in England dating back to the time of King Inne. However, others claim that it originates near Charleroi, Belgium. It is not proven yet if the name originated in England, spreading across the English Channel after the 13th Century, and subsequently spreading farther eastward into Germany at some later date, but it appears likely.
Does anyone have any information on the origin of these Belgian BASTINs, whether in more recent times, or during the middle ages?
