Who was the gossipy neighbor who seemed to know everything in To Kill a Mockingbird?

The "neighborhood scold," Miss Stephanie Crawford lived
nearby the Finches and seemed to have her nose in everyone's business. If there was
gossip in the neighborhood, Miss Stephanie was bound to know about it, and many of the
terrible rumors about Boo Radley came from her. In fact, Miss Maudie tells the children
that most of the rumors are " 'three-fourths colored folks and one-fourth Stephanie
Crawford.' " We know that she is pushing 60 and is a bit overweight. When the children
build their snowman, they note that it resembles Miss Stephanie. After Miss Maudie's
house burned down, she relocated temporarily in Miss Stephanie's
home.
