If he was born in the House of Hohenzollern then wouldn't that be his actual surname and shouldn't that be included in his full name? i.e., William Frederick Louis Hohenzollern. Please clarify. Thanks.
Even if he did not used it as a surname though, wasn't it still legally his name? Or was that name officially dropped somewhere along in the order of succession?
Is he in English really called Wilhelm I of Germany? He was king of Prussia! In German he is called Wilhelm I, König von Preußen (Prussia) 82.82.117.83 23:30, 12 Nov 2003 (UTC)
I've mostly heard him called Wilheim I not William I. —Preceding unsigned comment added by 204.52.215.67 (talk) 17:44, 16 October 2007 (UTC)
Yes, in english he is usually reffered to as William I of Germany, not wilhelm. Not even his grandson is called wilhelm in textbooks. The page title should reflect this. -Alex, 12.220.157.93 00:25, 28 January 2006 (UTC).
