In 1917, the British royal family renounced all of their ties to Germany and decided to change their name to “Windsor.” Prior to this, the royals didn’t have a public last name, although the British National Archives said they used “Wettin” as their formal name. Before landing on Windsor, names like “Tudor-Stewart,” “Plantagenet,” “York,” “Lancaster,” “D’Este,” “Fitzroy,” and even “England” were considered.
