I was under the impression that the Mormon Father God had one wife for each of the worlds that he populated. That way all of the souls that came to our earth would be from only one of his wives, which would be our Heavenly Mother. However, I haven't discussed this point with a Mormon or researched that question.
Neither have I, but Orson Hyde preached about Jesus' polygamous wives:
"I discover that some of the Eastern papers represent me as a great blasphemer, because I said, in my lecture on Marriage, at our last Conference, that Jesus Christ was married at Cana of Galilee, that Mary, Martha, and others were his wives, and that he begat children."

Some commentators have speculated about the identity of the unnamed bridegroom. ...
Bishop John Spong suggests in his book
Born of a Woman that the event was actually the wedding of Jesus himself to
Mary Magdalene.
[8] In 1854, at a time when
polygamy was an element of mainstream practice of
The Church of Jesus Christ of Latter-day Saints, the
Latter-day Saint elder Orson Hyde made a similar suggestion, arguing that Jesus was a
polygamist and that the event at Cana was his wedding to Mary Magdalene,
Martha and
Mary of Bethany.

Marriage at Cana - Wikipedia
We will turn over to the account of the marriage in Cana of Galilee, and the mother of Jesus was there. Yes, and somebody else too. You will find it in the 2nd chapter of John's Gospel; remember it and read it when you go home. “And the third day there was a marriage in Cana of Galilee; and the mother of Jesus was there: And both Jesus was called, and his disciples, to the marriage. And when they wanted wine, the mother of Jesus saith unto him, They have no wine. Jesus saith unto her, Woman, what have I to do with thee? mine hour is not yet come. His mother saith unto the servants, Whatsoever he saith unto you, do it. And there were set there six water pots of stone, after the manner of the purifying of the Jews, containing two or three firkins apiece. Jesus saith unto them, Fill the water pots with water. And they filled them up to the brim. And he saith unto them, Draw out now, and bear unto the governor of the feast. And they bare it. When the ruler of the feast had tasted the water that was made wine, and knew not whence it was: (but the servants which drew the water knew); the governor of the feast called the bridegroom, And saith unto him”—that is, the ruler of the feast saith unto the bridegroom, “Every man at the beginning doth set forth good wine; and when men have well drunk, then that which is worse: but thou hast kept the good wine until now.”
Gentlemen, that is as plain as the translators, or different councils over this Scripture, dare allow it to go to the world, but the thing is there; it is told; Jesus was the bridegroom at the marriage of Cana of Galilee, and he told them what to do.
Now there was actually a marriage; and if Jesus was not the bridegroom on that occasion, please tell who was. If any man can show this, and prove that it was not the Savior of the world, then I will acknowledge I am in error. We say it was Jesus Christ who was married, to be brought into the relation whereby he could see his seed, before he was crucified. “Has he indeed passed by the nature of angels, and taken upon himself the seed of Abraham, to die without leaving a seed to bear his name on the earth?” No. But when the secret is fully out, the seed of the blessed shall be gathered in, in the last days; and he who has not the blood of Abraham flowing in his veins, who has not one particle of the Savior's in him, I am afraid is a stereotyped Gentile, who will be left out and not be gathered in the last days; for I tell you it is the chosen of God, the seed of the blessed, that shall be gathered. I do not despise to be called a son of Abraham, if he had a dozen wives; or to be called a brother, a son, a child of the Savior, if he had Mary, and Martha, and several others, as wives; and though he did cast seven devils out of one of them, it is all the same to me.
