Explain the possible allusions or symbolism of the characters names.Delacroix Graves Summers Bentham Hutchinson WarnerMartin

Each of the characters you listed could be considered an
example of symbolism, some of which are very obvious.  For example, Mr. Summers and Mr.
Graves have surnames that are even symbolic; they are in charge of the lottery, which
takes place in the summertime and results in a new grave due to the death of the
"winner."  In addition, Mr. Summers is the administrator of the lottery
and

...Every
year, after the lottery, Mr. Summers began talking again about a new box, but every year
the subject was allowed to fade off without anything's being done.  The black box grew
shabbier each year:  by now it was no longer completely black but splintered badly along
one side to show the original wood color, and in some places faded or
stained.

Mr. Summers'
attempts to convince the townspeople to make a new box are symbolic of those in society
who consider the lottery important, such as Old Man Warner.  However, his prodding does
not produce a response.  The condition of the black box represents the practice of
conducting the lottery, which "some places have already quit."
