What is the significance of the following characters in To Kill a Mockingbird: Scout, Atticus, Jem... ... Mr Ewell, Dill, Miss Maudie...

SCOUT.  She serves as
narrator and protagonist. Her loss of innocence is a key theme of the
novel.

JEM.  As Scout's older
brother, he serves as her companion. Jem's growth into adolescence causes him to drift
apart from Scout a bit by the end of the
novel.

ATTICUS.  The
conscience of Maycomb, Atticus serves as the role model not only for his children but
also for everyone else in the town. He is one of literature's most famous
attorneys.

BOB EWELL.  Bob is
the dastardly villain of the novel: a drunken, racist, vengeful man who is perfectly
willing to take out his anger on children and
women.

DILL.  Dill is one of
the human mockingbirds of the story--the best friend of Jem, Scout's fiance, and a
storyteller of renown. However, his parents have no time for him, creating a sadness in
the boy that grows as the story
evolves.

MAUDIE ATKINSON. 
Longtime friend, neighbor and supporter of Atticus, and a loyal adult friend to his
children.

CALPURNIA.  The
Finch's maid, she is considered a member of the family by
Atticus.

AUNT ALEXANDRA. 
Atticus' stuffy sister, she comes to stay with the Finch family during the Tom Robinson
trial and never leaves.

MAYELLA
EWELL.  The woman who falsely accuses Tom Robinson of rape, she actually
lures Tom into her home and kisses him. She is a lonely, pitiful woman who, in spite of
her terrible crime, nevertheless is a sympathetic
character.

LINK DEAS.  A
relatively minor character, he is Tom's (and his wife's) boss who speaks up for Tom in
court.

MRS.
DUBOSE.  A mean old woman, it is revealed that her bad
moods are caused by her desire to rid herself of her longtime morphine addiction. She
dies drug-free after Jem has been forced to visit her each day, reading by her
bedside.

HECK TATE.  The town
sheriff, Heck is not remarkable, but he makes a wise decision at the end of the novel,
saving Boo Radley from the publicity of an investigation following the death of Bob
Ewell.

MR.
UNDERWOOD.  The town newspaper editor, he hates Negroes,
but he is ready to defend Atticus and Tom when the lynch mob arrives at the
jail.

DOLPHUS RAYMOND.  A
wealthy white man who lives with his Negro mistress, Raymond is one of Maycomb's most
unusual characters. He befriends Scout and Dill during the trial and reveals his secret
about the bottle-in-the-bag.
