Katherine was born in the year 1676 as the oldest daughter to Mark and Melissa. As she grew up she helped her mother around the house and often took care of her younger sisters. Shortly after her 16th birthday, she fell in love with a local boy and soon married him. However the two newlyweds shortly left Salem, in search for more work opportunities.
As noted by Christian, Katherine is a very devot Christian and spends much of her free time studying the bible. However, she believes that work and responsiblities should not dictate someone's life, and that people should make time to relax and have fun.
