When watching Turn, I noticed that Robert Rogers' outfit was called The Queen's Rangers despite this being in the time of King George III. I assumed they had a history dating back to Queen Ann, but Wikipedia indicated they were formed as Rogers' Rangers during the French and Indian War.
What gives?
Because the King was married. It was common practice at the time for important personages to have units which honored them. In this case, it would be in honor of the Queen Consort at the time, Charlotte.
Digging out a few other examples of regiments honoring people other than the King.
The Duke of Albany's Own Highlanders, aka the 72nd Regiment of Foot, honoring the King's brother Frederick.
49th (Princess Charlotte of Wales's) (Hertfordshire) Regiment of Foot, after the daughter of the future king George IV.
The Duke of Edinburgh's Royal Regiment (which is the flip side of the Queen's Rangers, as the Duke of Edinburgh is the royal consort of QEII).
I think you get the point. A lot of British regiments are/were named in that style, and in this case it simple was to honor the Queen, even if she was only the consort and not the ruler.
