Krystyna Ceynowa, also spelled as Cejnowa (died 1836), was an ethnic Polish victim of murder by lynching and an alleged witch.
Accused of sorcery, she was subjected to the ordeal of water and drowned in Ceynowa (today Chałupy).
She was regarded as suspicious by the community for various reasons, including the fact that she never went to church, and it was said that black crows were attracted to her chimney.
To the disbelief of many, she remained afloat for a long time, which was taken as an evidence of witchcraft, as none realized that her gown and skirt had acted as a buoy.
When Ceynowa did not drown, the people found her to be a real witch and killed her with their paddles[2] or (according to another account) she was stabbed to death.
