Thanks a lot. I went to your directed site Utah History to Go and have extracted the following information:
According to Church of Jesus Christ of Latter-day Saints (LDS) historical records, Brigham Young was sealed to as many as 56 women. Many of the wives to whom Young were sealed were widows or elderly women for whom he merely cared or gave the protection of his name.
When asked by Horace Greeley in 1859, Brigham Young said that he had 15 wives, "but some of those sealed to me are old ladies whom I regard rather as mothers than wives. . ." This answer reflects the complicated nature of the definition of "plural wife." As to the number of wives with whom it is known that he had conjugal relations, sixteen wives bore him 57 children (46 of whom grew to maturity).
Several of his wives lived in the Lion House or the Beehive House; others had separate residences.
At the time of his death on August 23, 1877, Young had married 56 women--19 predeceased him, 10 divorced him, 23 survived him, and 4 are unaccounted for. Of the 23 who survived him, 17 received a share of his estate while the remaining 6 apparently had non-conjugal roles.
The question is, has the present-day American civil society allowed this kind of practice or the laws of the USA today have put an end to it?
