Theano "Theo" Mae Demas Sigford, age 91 of Tower/Soudan, died November 4, 2021 in Cook Care Center in Cook, Minnesota.  She was born January 8, 1930 in Aberdeen, South Dakota the first child of Anthony "Tony" Demas and Emma (Potter) Demas.

Theo graduated early from high school in Aberdeen, South Dakota, in 1947, then left college early and moved to Minneapolis, MN in 1950 where she became a legal secretary and, ultimately, the support staff/office manager for a major international law firm in the Twin Cities. She retired and married Robert "Bob" Sigford in 1977.  For many years they enjoyed their cabin on Lake Vermilion, scheduling their lives to be on the lake three days a week, year round, as long as they could cross either by boat or snow mobile.  In 1985 they retired fully to a home on Lake Vermilion in the Tower-Soudan area. Bob passed away in 2005 and Theo lived out her life on the lake and in the community that she had come to call her home.

She was a voracious reader and both supported and made constant use of the Arrowhead Library System's Bookmobile, sang in local choral groups, volunteered as a tax preparer, volunteered for the Tower Soudan Historical Society and supported the restoration of the Fire Hall on Tower's Main Street.  She volunteered for the Tower food shelf, volunteered reading to school children, hand-knitted a mountain of colorful wool socks, played organized bridge with friends, and even occasionally went line dancing.

Theo was preceded in death by her parents and her husband, her three younger siblings, George Demas, Marian Demas, and Tyrus Demas. She is survived by her nephew, Dodd Demas, niece Lisa (Demas) Jones, niece Kristin Sigford, nephews Rolf Sigford and Steven Sigford, niece Ann Sigford, nephews Dale Sigford and David Sigford.

By her preference, there will be no service, but a gathering of family and Tower/Soudan friends will be scheduled in the summer of 2022 when remote relatives are able to travel to Northern Minnesota.  Donations in memorial are encouraged to organizations she has supported over many years: Minnesota Public Radio of St. Paul, MN, Advocates For Family Peace of Grand Rapids, MN, Minnesota Center for Environmental Advocacy of St. Paul, MN, The Mesabi Humane Society of Virginia, MN, or Planned Parenthood of Minnesota, North Dakota, and South Dakota, of St. Paul, MN.
