Sally Conrad was hired by Mary Whitmer in June of 1829 to help around the house while Joseph Smith and Oliver Cowdery were translating the Book of Mormon. Although Sally didn’t see the plates she did see Joseph and Oliver around the house.
She said she saw the men
come down from the translating room several times when they looked so exceedingly white and strange– Sarah (Sally) Heller Conrad, as recorded by Oliver B. Huntington (1897)
Sally eventually joined the church which suggests she didn’t notice anything fraudulent from Joseph and Oliver. Wouldn’t we expect those who were around Joseph during translation to have a good grasp of whether it was fraudulent or spiritual? How do we explain Sally’s experience of Joseph and Oliver?
