Dear Katherine,
I have FABRICIUS and ENGEL in the area of Malchin, but no marriage between this families.
There was a Johann Andreas FABRICIUS who was born in Magdeburg and who came in 1760 to Bützow. I do not know where he stayed until 1760.
Tomorrow I want to go to the library and then I look for your ENGEL - FABRICIUS marriage in the pages of the ENGEL gemealogy which I have not copied.
kind regards,
Christoph
