Family couple, sorry, the quartet! Twin sister Vicki and Valerie married to a man named Joe, who still married but them and their cousin - Alina!
Happy family lives in Salt Lake City. Until someone did not come: they were Mormons and fundamentalist in terms of their religion, polygamous marriages are permitted. They are respectable family, have 24 children.
While polygamy is prohibited by law in all states to prosecute polygamists are quite rare.
