Sylvia Ann Simons was born August 15, 1931 in Volga, SD, the younger of two children born to Selmer Samuel Simons and Carrie (Askvik) Simons. She grew up a farm girl in Lake County, and graduated Valedictorian from Rutland High School in 1949.

Sylvia worked side by side with Vincent on the family farm. In addition, she worked more than 25 years as a Chiropractic Assistant for her second son, Dr. Douglas Caron. Sylvia fostered 11 children throughout the years, caring and nurturing them in ways only she could. She was of Norwegian descent, and was so very proud of her heritage. She looked forward to the family tradition of making Norwegian Lefse, every holiday season. She loved to dance, and traveled the world over, with her dance partner Vincent by her side. In their later years, they traded the world for senior centers, and they maintained a very active social life. Sylvia was fun loving and exciting. She loved to travel and play cards. She will be dearly missed!
