Are Boo Radley and Tom Robinson related in To Kill a Mockingbird?

Tom Robinson is an African-American man, married with
children, who lives in the Negro Quarters just outside Maycomb. Arthur "Boo" Radley is a
white man, single and with no children, who lives in Scout's neighborhood. Aside from
the fact that they symbolically represent two of the innocent, human mockingbirds in
Harper Lee's To Kill a Mockingbird, and that their stories--Tom's
rape trial in which he is defended by Atticus, and the Finch children's fascination with
the unseen Boo--serve as the focus for the two parts of the novel, Tom and Boo are NOT
related.
