I am currently teaching Tom Sawyer and my students brought up a question
that I have been unable to answer. We know from the text that Mary and
Tom and Sid are cousins and that Sid and Tom are half brothers and sons
of Aunt Polly's dead sister. But whose child is Mary? I've looked and
looked and have not come up with an answer. There probably isn't one . .
. but I told my students I'd ask.
