Sugar Hoarder‘s title: Schmidt-Lötzen translates this as Oberhofmarschall, not Oberhofmeister.

¯\_(ツ)_/¯

Is there a huge difference? He seems to be the guy in charge of the courtiers either way. At least enough, I would think, to make the identification.

Lehndorff might not have been interested in Hans Herrmann, but he sure delivers on gossip about Hans Herrmann‘s family, doesn‘t he?

He sure does! Of course I wish he did both, but since he's supplying what no one else did, in a way that's even better? Because at least then Hans Hermann has some family members, which comes in useful for fic. (I was going to say, family members that are more than just names, but we didn't even have their names until we started trying to figure out how Lehndorff's gossip targets were related to our Hans Hermann!)

I will check out the volume register, if there is one, but it might be a while - I‘m on the road pretty much the entire next week.

No rush, just offering to do more research to satisfy your curiosity if I have more data. :)

I suspect more of general Fritz paranoia and/or spite re: his nephew.

Agreed. Fritz's control issues come to the fore whenever his heir is concerned: zero chill whatsoever.
