So why are you discrminating on age if that is what they agree on!
there are times it has nothing to do with power or whatever else you might conclude sometimes it is just plain LOVE!
I was going to ask some rhetorical questions having to do with blinders that leads to historical revisionism, but decided to pass on that.
Do you want to explain how it was that Helen Mar Kimball, wife No. 24 of Joseph Smith, had time to fall in "LOVE!" w/Smith? Kimball was the ninth wife Joseph Smith married between March 4 and the end of Spring, 1843! You're telling me that Smith just ignored his 8 other brand-new brides (not to mention eight others married in 1842) to foster this whirlwind courtship?
Nope. Records show that Kimball's father, Heber C. Kimball, who himself eventually took 39 wives, brokered the deal.
If you go to http://www.wivesofjosephsmith.org/26-HelenMarKimball.htm, it reads: "In 1843 Apostle Heber C. Kimball had an important talk with his only daughter, fourteen-year-old Helen Mar. She wrote: 'Without any preliminaries [my Father] asked me if I would believe him if he told me that it was right for married men to take other wives...The first impulse was anger...my sensibilities were painfully touched. I felt such a sense of personal injury and displeasure; for to mention such a thing to me I thought altogether unworthy of my father, and as quick as he spoke, I replied to him, short and emphatically, No I wouldnt!...This was the first time that I ever openly manifested anger towards him...Then he commenced talking seriously and reasoned and explained the principle, and why it was again to be established upon the earth. [This] had a similar effect to a sudden shock of a small earthquake.'
"Then father 'asked me if I would be sealed to Joseph...[and] left me to reflect upon it for the next twenty-four hours...I was sceptical-one minute believed, then doubted. I thought of the love and tenderness that he felt for his only daughter, and I knew that he would not cast her off, and this was the only convincing proof that I had of its being right. I knew that he loved me too well to teach me anything that was not strictly pure, virtuous and exalting in its tendencies; and no one else could have influenced me at that time or brought me to accept of a doctrine so utterly repugnant and so contrary to all of our former ideas and traditions.' Unknown to Helen Mar, Heber and Joseph had already discussed the prospect of Helen Mar becoming one of Josephs wives. Heber now sought her agreement. Helen recalls, 'Having a great desire to be connected with the Prophet Joseph, he offered me to him; this I afterwards learned from the Prophets own mouth. My father had but one Ewe Lamb, but willingly laid her upon the alter.'"
The next morning Joseph visited the Kimball home. '[He explained] the principle of Celestial marrage...After which he said to me, If you will take this step, it will ensure your eternal salvation & exaltation and that of your fathers household & all of your kindred.[] This promise was so great that I willingly gave myself to purchase so glorious a reward. None but God & his angels could see my mothers bleeding heart-when Joseph asked her if she was willing...She had witnessed the sufferings of others, who were older & who better understood the step they were taking, & to see her child, who had scarcely seen her fifteenth summer, following in the same thorny path, in her mind she saw the misery which was as sure to come...; but it was all hidden from me.' Helens mother reluctantly agreed and in May of 1843, Helen married Joseph Smith." During the winter of 1843-44, there were weekly parties at Joseph Smiths Mansion House. Many of Helens friends attended, as well as her sixteen-year-old brother William. Disappointed, Helen wrote, 'my father had been warned by the Prophet to keep his daughter away...I felt quite sore over it, and thought it a very unkind act in father to allow [William] to go and enjoy the dance unrestrained with others of my companions, and fettered me down, for no girl loved dancing better than I did...and like a wild bird I longed for the freedom that was denied me; and thought myself an abused child, and that it was pardonable if I did murmur.'" "...Helens father would eventually marry thirty-nine wives. She wrote, 'I had, in hours of temptation when seeing the trials of my mother, felt to rebel. I hated polygamy in my heart.' Helen later fell victim to a prolonged illness: For three months I lay a portion of the time like one dead...I tasted of the punishment which is prepared for those who reject any of the principles of this Gospel. Eventually she was converted to polygamy and recovered from her illness, I fasted for one week, and every day I gained until I had won the victory...I learned that plural marriage is a celestial principle, and saw... the necessity of obedience to those who hold the priesthood, and the danger of rebelling against or speaking lightly of the Lords annointed."
The site goes on and includes a poem later written by her.
The same questions arise for Brigham, who married the Bigelow sisters (aged 16 and 19) the same month--March of 1847. They were wives No. 20 & 21. Ellen Rockwood, wife NO. 14, was thought to have been 16 and was also part of a double-bonus marriage month for BY (Jan, 1846). 15 yo Clarissa Decker was wife No. 6. In less than 5 years (June, 1842 to March 1847) Brigham married 19 additional wives--an average rate of a new bride for every new season of the year. I guess "love was in the air" so much that it was contagious in the 1840s.
