What might cause Goody and Francis Nurse to be accused of witchcraft?

Once the rumors or witchcraft begin, it is easy for people to start pointing fingers at others. Rebecca was present for the delivery of Mrs. Putnam's babies, thus, she is an easy target for the bereaved mother, who cannot accept the deaths of her infants.

Francis was not accused of witchcraft, though, it is believed that his intervention in a land dispute was part of the reason for the accusations against his wife.
