Could happen, though; didn't Fredersdorf specify female inheritance in his will?
I think so? As did Knoblesdorff of course, but I feel like an old family like the Knyphausen's might have their own rules. But hey, it's perfectly possible if the chronicle says so and since, as I said, none of Ariane's brothers had kids.
(Speaking of inheritances - I checked the Brandenburg archive where Engel found Knobelsdorff's testament, just in case there was a digitized version. There wasn't of course, just the database entry, but I found some other things listed: Peter's mother-in-law's will from 1750/51, four different last will entries for Carl Ernst Reinhard v. Keith, chamberlain (1x 1806 / 3x 1812), and: lots of Zernikow related documents, including the deed of gift from June 1740, and a copy of Fredersdorf's will with additional documents about inheritance negotiations - there seem to have been some disputes (even without an unlikely Deschampes claim in the mix :P), which got settled in 1760. None of these are digitized, but still interesting to know.)
But if Carl Ernst Reinhard was lord of the manor, he just *might* have been buried there.
But only after Ariane and all her brothers were dead themselves, decades later - and since she herself was buried in Berlin, I'd say the chances are slim to none that Peter wasn't.
