Oh, it's definitely not Peter. The only Keith under discussion here is Karl Ernst! Mentioning Peter was just my wishful thinking reasoning that if the Knyphausens had a portrait of the son, they might have a portrait of the father!
And to make a case that it might have been Karl Ernst: this is the schloss at Jennelt, where Karl Ernst has just been lord of the manor for 30+ years. And he might have been emotionally close to his heir and said heir's immediate family. And, as such, the painting might even have been recent enough for modern tastes! Plus, as owner of an estate, maybe he could have splurged on having his portrait done (maybe that's why his house was so run down, he prioritized the painting :P).
BUT.
If you say it's grammatically possible to be a work of art from his collection, then I agree that's waaaay more likely as a main painting of choice. (Plus judging by the correspondence I've read, these people don't seem to be super devastated that their cousin who lives on the other side of Germany died, and the overall impression I'm getting is distant relatives, not closely bonded.) I just wasn't sure if it was possible.

Thank you for clearing it up.
