Dear Bernd,
Thanks for the suggestion, that's a great find.
There's a good chance that Hans CRIVITZ is related to my Anna Dorothea KRIWITZ, most likely her father, as you suggest.
Furthermore, at the baptism of their first child in September 1758 in Rothspalck, the first witness was v. Thomstorff, the same as listed at milhahnspurensuche.
Cheers,
Fred
