Maria Catharina Krull ( van de Kaap)

hi all,

I am trying to trace Maria Catharina Krull, partner / spouse of one Carel Oostewalt . I presume that he was a German but can't find anything on him either. They had a daughter Carolina Christina Wilhelmina (1804 -1840) who married the progenitor of the Freysen family , Tomas Freisen.

Help please?
