Hi J.S.
I don't know whether my Knigge will fit in with those you are looking for.
What I have is:
Christine Marlene Knigge, born 1735, died 9 August 1788. Daughter of
'Ackermann' (farmer) Johann Friedrich Knigge from Fallersleben.
She married Heinrich Dietrich Brakebusch, dob: 1726, died 4 May 1789. He had
a water mill in Barum near Wolfenbuettel. Previously he owned another mill
at Zellerfeld. He was divorced from his first wife by desertion judgement,
and married Christine Marlene Knigge on 21 November 1759.
They had 3 children:
1. Johann Tobias Wilhelm Brakebusch, dob: 12 Sep 1764, died 11 May 1818. He
had a water mill and married (22 July 1790) Marie Dorothea Loehr. (and I
have his descendents)
2. Marie Elisabeth, dob: 28 March 1767, married 7 March 1791 miller Nikolaus
Heinrich Kruse of Bennigsen.
3. Christine Margarethe, married miller Johann Heinrich Banse of Wennigsen
on 22 June 1790.
Hope this helps and fills a hole in your search.
