What are the external conflicts in Witch of Blackbird Pond?

To me, there are three major external conflicts in this book.

First, I think there is a conflict between Kit and society in general when she moves to Connecticut from Barbados.  She finds that things are much different in her new home, as seen when she finds out that swimming is associated with witchcraft.

Second, there is the conflict between Kit and Hannah on the one side and the Puritans on the other.  This is connected to the first conflict.

The last conflict I see is between the colonists and the Crown as the colonists oppose the attempts to change their charter.
