Thetta, the first child of Rodney and Arlene (Geu) Mathewson, was born July 5, 1949 in Sidney, NE. She attended Sidney Schools until third grade when the Herdon School District consolidated with Potter. After graduating from Potter in 1967, Thetta attended Kearney State Teachers College where she earned her bachelor’s degree in education and later her master’s degree in education.

Thetta started her teaching career at Wolbach then moved to Grand Island where she retired in 2013 after 41 years of teaching, making many lifelong friends along the way. She split her time between Sidney and Grand Island for a while but ended up in Sidney where she took care of her parents for 5 ½ years, and where the patience she had for teaching young children was once again lovingly applied.

Thetta was an active member of Delta Kappa Gamma, serving on most committees and as an officer; she was the chief organizer of the 5:03 Club, a collection of friends; and she was a member of Trinity Methodist Church in Grand Island. A talented musician, Thetta sang in church choir and was the summertime organist at Potter Methodist Church for many years. She was also a talented seamstress and made many gifts for friends and family. She loved giving gifts and made it her quest to find just the right gift for everyone on every occasion.

Thetta shared many stories of her students and her dear friends at school. She also enjoyed spending time with her nieces and nephews. Always the teacher, she helped them learn piano, sewing, ping-pong, and many other practical skills. She enjoyed reading, crossword puzzles, Scrabble, Sudoku, and genealogy. She was known for her infectious, ready laugh and sense of humor.

Thetta was steadfast and consistent about connecting with friends and family. She was a caring daughter, fun sister and loving aunt who will be dearly missed by all.

She is survived by siblings Loretta Flohr and Randy wife Gina Mathewson; nephews Justin and wife Kindra Flohr and Ben and wife Carly Mathewson; nieces Kristin Davis and Shelby Mathewson; Beau’s wife Kahla Mathewson; and great-nieces and great-nephews Luke Mathewson, Leyla Bermudez, Isla Mathewson, Henry Mathewson and Miles Mathewson.

Thetta was preceded in death by parents Rodney and Arlene Mathewson and by nephew Beau Mathewson.
