We don't have any information about how Kelly and Marie lived before Nick was born. Once Kelly became the guardian of the Coins of Zakynthos and a mother, she appeared to be hiding out in the guise of a suburban softball mom, and we know that Marie walked away from the grimm life to become a librarian and raise Nick. Kelly becoming a mercenary once she went on the run makes perfect sense; those knights errant of old took payment for their deeds as well.
