Short video about when Joseph first began to think about polygamy. First revelations on the topic were before 1832.
Joseph Smith polygamy expert, Don Bradley reviews the timeline associated with this marriages and surrounding details, including those about possible pregnancy with Joseph.
Don highlights events in 1836 with Fanny showing signs of pregnancy in July 1836. Emma was a major player in getting Fanny out of the Smith home around that time.
Gospel Tangents discusses the restoration of the priesthood in 1829, and its relevance to Fannie Alger. Peter, James, and John bestowed the Melchizedek Priesthood. That fact in 1829 helps answer this question: was Fannie sealed to Joseph and with what authority?
Elijah restored the keys to direct others to seal and be sealed. This occurred in Kirtland in 1836. Keys are not priesthood. Joseph held the priesthood since 1829.
Though Joseph didn’t orally share the Elijah Kirtland visitation, it was immediately dictated and put in a journal.
A candid discussion about the young women Joseph married:
Side (but relevant) note: a non-LDS miller — Jacob Hawn of Hawn’s Mill, Missouri — married a woman at the age of 15. Jacob’s first wife died, and Jacob 2nd wife was 15. Young for us, but not too young for that time.
There is no solid evidence of sexual relations with women Joseph was sealed to by eternity-only ordinances, including young Helen Mar Kimball. Helen was 14 years old when sealing occurred. Significant evidence exists, however, for Jacob Hawn (wife was 15), Edgar Allen Poe (wife was 13), and others of that time did have sexual relations with their young wives.
