Thomas Farriner BAKER To King Charles II

------------------
Is this grammatical? What is the role of the preposition 'to'?

If you put a comma after "Farriner" and don't use all-caps for "baker", this will be correct. You can use either "to" or "for" in that preposition's place.

Thank you for your help.

By the way, how do you pronounce "Farriner'?

I can't find the name in dictionaries.

I would pronounce his name like this:

fair'-in-er

Yes, the sentence "Thomas Farriner BAKER To King Charles II" is grammatical, but it appears to be missing some necessary elements to be a complete sentence.

The preposition "to" in this context indicates the recipient or destination of the subject's action. In this case, it suggests that Thomas Farriner, who is a baker, is the person directly associated with or providing services to King Charles II. The preposition "to" acts as a link between the subject (Thomas Farriner BAKER) and the object (King Charles II).

To complete the sentence, you could add a verb and some additional context. For example, "Thomas Farriner BAKER provided bread to King Charles II" or "Thomas Farriner BAKER was appointed as the baker to King Charles II."
