Apologies for the interruption..
I have been so entertained by this discussion, that I decided to join this site. But I wanted to take a short, regressive step in the content of this thread to correct an error Yanni. In post #204 you state that....'Care in the detail is equally important to any art, the one of finding the "errors" of professional history writers and archivist-interpreters included. Such is the case with the following "family site", caring not for the detail but to "name" their relative "sources" of "misunderstanding" nevertheless:'.
I am sorry to say that the source you quote is inaccurate and that Frederick Nicolay was appointed Page of the Backstairs to Queen Charlotte on the 5th September 1761 (source: Printed Lists, Royal Archives, Windsor), which makes the 10 year chronology (as well as the additional reference of poor Augusta Georgiana Louisa Nicolay) correct.
All things considered however, I am enjoying the overall, conspirital tone and le Comte de Saint-Germain is just the icing on the cake! Oh, just to muddy the water further, did you know that le Marquis Jean de Nicolay (d.1737) was private tutor to Voltaire?
