From my understanding, arranged marriages did happen between commoners/peasants for economical reasons. What I wanted to know was: could she be forced into this marriage (or essentially backed into a corner where any other attempts to marry anyone else besides who the family chose would be "denied")?

Can parents keep their daughter from marrying someone they wanted to marry? Also, what was the general process of proposing an arranged marriage and are the daughters/children involved in the contract planning at all or just the parents?
