We didn’t know of Ms Perkins, so we Googled, and it’s interesting how many different people named Elizabeth Perkins are connected with museums.  Only one in York, though, and Tripadvisor somewhat laconically describes her as “the founder of the Old York Historical Society, (and) used to spend time here with Mark Twain.”  We’ve no doubt there was more to her, and the house, than that.  Unused card.  Grade: 1
