When Scout, Jem and Dill all get together and go into town to see the scene at the courthouse, they arrive when everyone is out having lunch on the town square. They see Mr. Dolphus Raymond drinking out of a paper bag in one corner of the square and Jem explains what is going on.
He explains that Dolph, who is white, lives among the black community in Maycomb and that he has a black woman as a girlfriend, with whom he has had a number of children. He tells the story about his first marriage not happening because the bride-to-be killed herself prior to the wedding.
Jem explains that Mr. Raymond is well-off and came from a "real old family," which means a respected white family in Maycomb. He also notes that he takes very good care of his children and seems to be a well-meaning man even though the town looks down on him. He points out that it is hard for the children being "mixed" and that Dolph has sent a couple of them up north where folks don't seem to mind so much.
