The chimney sweeper by William blake

One of the few named characters in Songs of Innocence, Tom Dacre is the young boy who cries at night after a hard day as a chimney sweeper. He eventually sleeps and has a dream of an Angel, who reassures him that his present suffering will end one day, and that he will be welcomed into an afterlife without pain. I think tom represent the sheep: small and meek. Also a reflection of innocence.
