Didn't a German branch inherit the English monarchy in the late 17th Century? That timing would work out -- people adapting whatever style the monarchs used as the standard.
Elector Georg Ludwig of Hanover became King George I of Great Britain in 1714. This happened because the Act of Settlement 1701 declared Georg Ludwig's mother, Sophia, the heir to the throne (this was done specifically to cut off Jacobite claims), but she died a month before Queen Anne (which was a shame: by all accounts she was brilliant, and she was a patron of the sciences), so the throne went to her son.
