I think Jana is the best looking of the sisters. Given that, and the general looks focused aspect of Gothard, I have to then believe that her still being single is either forced or completely her choice. I definitely don't believe that some man has never approached the family about "courting" her. It just doesn't make any sense. I hope that it's simply that the people who did approach her, she wasn't interested in and said a firm no, rather than selfishness on her family's part in a desire to keep her there to look after all of their kids.
