A New Fairfield family has been displaced by a fire and one person had to be transported to the hospital for evaluation.  Firefighters responded to the Hudson Drive home yesterday morning and it took about half an hour to put out the flames in the rear of the house.  Putnam Lake Fire and Patterson Fire also responded as the volunteer companies remained on the scene to make sure all hot spots were out. The New Fairfield Fire Marshal's Office is investigating the cause.  The garage and kitchen area sustained the most damage.
