From the Vancouver Sun:
One bride is Lorraine Johnson, an American, sent by her family to “marry” Blackmore, who was then the powerful bishop. She was his 18th wife. It’s not clear whether Johnson immigrated legally to Canada or simply came across the border and stayed.
The other bride is Shelina Palmer, a Canadian born into a polygamous family in Bountiful and assigned to Blackmore. She is wife number 22.
