She was born on April 23, 1936 in Random Lake, WI, a daughter of the late Ivo and Martha (Hansen) Thomas.
Theresa attended grade school at St. Mary's Catholic School and Random Lake High School. She was the big sister to six brothers. Not a week went by where she didn't speak of her brothers. She loved them all dearly.
