What were the names of the girls in the Pickwick Club? Where do they hold the Pickwick Club meetings?

Sisters Meg, Jo, Beth, and Amy create their own version of the Pickwick Club, based on the popular novel The Pickwick Papers by Charles Dickens.  Each sister plays a character from the novel during their club meetings, which involve reading the newspaper they create.  The oldest sister, Meg, plays Samuel Pickwick.  Jo impersonates Augustus Snodgrass.  Beth's character is Tracy Tupman.  The youngest sister, Amy, plays Nathaniel Winkle.  Later the four sisters vote to allow their neighbor, Laurie, to join them.  His character is Sam Weller.  The meetings of the Pickwick Club are held in the garret, which is the attic of the March house.  They set up a table and chairs in the attic room.  There is also a closet in the garret, which Laurie hides in.
