It was claimed at Comic Con that actual descendants of the Brothers Grimm reside in Portland. However there are no descendants of the brothers who compiled the fairy-tales, so the fan was mistaken or lying. Many people want to believe they are descended from the Grimm brothers, and the genealogists give the same answer - the Two Grimm brothers have no living descendants, Jacob had no children, and Wilhelm had no grandchildren, so their line ended there. However the Grimm family of Jacob and Wilhelm had more siblings who however were not working on the fairy-tales, e.g, their only sister Charlotte Grimm (1793-1833) who had 6 children, painter and copper engraver Ludwig Emil Grimm (1790-1863) or writer Ferdinand Philipp Grimm (1788-1845). So anyone who can actually trace their family back to a family called Grimm can only be (at best) a descendant of one of the brothers siblings. The surname Grimm does not mean someone is related to the Brothers Grimm; it was hardly a unique surname.
