What is Finch Landing in 'To Kill a Mockingbird'?

In Chapter 1 Scout tells us that Finch’s Landing is about 20 miles from Maycomb, where the story takes place. Atticus, whose last name is Finch, comes from Finch’s Landing, the place named after his distant relative Simon Finch.  Atticus left Finch’s Landing to study law and never returned. The significance of the name and place is that Atticus comes from a good family, in that they owned land and prospered, although not an aristocratic family.  This means a good deal to his sister, Alexandra.
