Carol was raised in Louisville and graduated from Westport High School. She went on to earn her Ph.D. in Sociology from the University of North Texas and spent many years as an Associate Professor at Tarleton State University, where she shared her passion for understanding society with her students.
In her spare time, Carol enjoyed bird watching, reading, horseback riding, and spending time talking with friends and family. She had a lifelong love of horses and horseback riding, which brought her great joy and occasional consternation throughout her life. She was a loyal University of Louisville Cardinals basketball fan and proudly wore red and black in support.
Carol was united in marriage to Jeff Mackinnon, who preceded her in death. She was also preceded in death by her parents; her brothers, Terrance and Ronald Key; and her nephew, David Key.
She is survived by her daughter, Cory Sills and husband, Paul Watts; granddaughter, Vivian Watts; stepson, Ian Mackinnon; nieces, Leslie Stepro and Amy Brewers; and nephew, Marc Key.
Carol will be lovingly remembered by her family and friends as a feminist who cared deeply about the world. She spoke her mind, stood her ground, and approached life with resilience. Her strength, independence, and unmistakable personality left a lasting impression on all who knew her.
