It's quite a story. Those people were tough.

The way I hear it is that "wagon train to Utah" is the reason the
Mormons got multiple wives in the first place. Husbands died on the
trail to Utah, killed by Indians, died of diseases, accidents and
sometimes just plain murder by their fellow wagoneers. The remaining
families would "take in" the families that lost their husband/father.
The mothers would become the additional wives to the remaining men. It
was out of necessity and human spirit to help the fellow man/woman, and
some of them dead guys just plain left behind cute wives. sic g
