hi, i have encountered this article http://www.guardian.co.uk/society/20...musicians-tour
there is written this:
Khosroujerdy's parents considered their blind daughter to be a punishment from God. They beat her and forced her into a marriage with a man who already had two wives, though the four of them did not all live in the same house. "It was a very unhappy situation," she recalled. "Whenever I was depressed I would sing to myself but it was impossible to imagine I could sing in public."
how should I understand this?: ...a man who already had two wives, though the four of them did not all live in the same house...
isn't there a typo? how can there be FOUR wives of TWO? if it is OK, can you explain me the meaning?
