Marie Catherine Florentine DUFRESNE married Jacques Joseph DUCROCQ, a widower, in Tilques on January 17th 1810.
According to her marriage record, she was born on February 22th, 1772 in Aix-en-Ergny.
No proof so far, that she is the same as Florence DUFRENE.
Her widower remarried in 1812 with Marie Jacqueline Françoise HOYEZ. In the marriage record (26/10/1812), his former wife is mentioned as the late Florentine Joseph DUFRESNE.
We can assume that her given name was Florentine.
She gave birth to a son, Jean Baptiste DUCROCQ around 1810
