Edward Stevenson claims he heard Joseph teach that the Godhead consists of Elohim, Jehovah, and Michael.

Our Father Adam, (the father of our spirits,) he is michael; he will call his children together (in Adam-ondi-Ahman Davis Co. Mo.) and hold a council with them to prepare them for the coming of the Son of Man. He (Adam) is the Father of the human family, and presides over the spirits of all men <and> all that have had the keys must stand before him in this grand council. This may take place before some of <us> leave this stage of action. . . Joseph Smith was the first, whom I ever herd proclaim a plurality of Gods, he said that there was Elohiem God, <and> Jehovah God, <and> Michael God, that there was Gods many <and> also many Lords, & God to every Earth as well as a Saivour to redeem them.
