Dolores Grimm was a member of the Grimm family, through her marriage to Douglas Grimm I. As she was the only daughter-in-law of Wilhelm Grimm and Henrietta Grimm, it can be assumed that she was well acquainted with the family business of being fairy-tale detectives. She is the great-great-great-great grandmother of Sabrina and Daphne, the protagonists of The Sisters Grimm series.
