Bealdwine = Baldewyne = Baldwin
It's been said that the name Baldwin means "brave, bold friend" and originated from Old High German, the earliest form of the German language which developed and appeared during the years 700 to 1050 AD. Variant early spellings can look something like Bealdwine or Baldewyne or Baudouin, as well as many others. English itself is a Germanic language, and the earliest Baldwins I can find appear in the area near Chesham in England. The Baldwins' origins therefore seem thoroughly European, and the name appears in many well kept records, centuries old (which is the only reason why I am able to share this information today).
