John Holbrook and Kit Tyler of The Witch of Blackbird Pond both travel to Wethersfield on the Dolphin. John is about the same age as Kit, and he is a Puritan interested in making a life for himself as a reverend. He is an intellectual, but he has had to study on his own, being unable to afford the fees to become formally educated. John's attachment to the Reverend Dr. Bulkeley holds him back from developing his personality and his own direction in life, and it is not until he separates himself from the reverend that he can become his own person. This struggle to be his own person manifests in the decisions John must make around his own marriage; though he loves Kit's cousin Mercy Wood, it is Mercy's strong-minded sister, Judith, who pursues John. By the end of the novel, John is able to stand on his own proverbial two feet and marry the woman he loves, proving he can actually be an independent person.
