Joseph E. Johnson reported that he knew that “the first frigging [slang for sexual relations]—that was done in his house with his mother in law—by Joseph.”1 Johnson’s statement represents the only available evidence regarding a possible relationship between Joseph Smith and Mary Heron Snider.

The fact that Mary Heron was not sealed to her legal husband, John Snider during their lifetimes, even though the opportunity was repeatedly available (including by proxy between her 1852 death and John Snider’s 1875 passing), is consistent with a sealing between her and the Prophet. John Snider remained an active Latter-day Saint, suggesting either that he was entirely unaware of the relationship (which is unlikely if his son-in-law, Joseph E. Johnson, knew about it) or that he knew about it and supported it.
