Our precious mother and grandmother, Annie Ruth Zweifel Gillis, passed away on January 8, 2022 surrounded by love at the age of 95 in Lake Jackson, Texas. An active member of the Church of Jesus Christ of Latter-day Saints, she was known for her devotion to her children and grandchildren, temple and missionary work, and for enthusiastically sharing her testimony of Jesus Christ. She was an avid reader and talented painter. She is survived by her sister Thelma McKinlay, her brother Frank Zweifel, her five children, Carol Ann Wood, Mahlon, Mark, Keith and Paul Gillis, 23 grandchildren and 41 great-grandchildren.

Ann Ruth Gillis was born on February 24, 1926 in Dubois, Idaho, one of eleven children. As a child she loved to play in the sawdust with her brother Glen and her sister Thelma. When she was old enough to go to school, her mother drove a covered wagon drawn by horses eight miles taking her and the neighboring children to school. As a young girl, she loved volleyball and basketball. During World War II, she worked as a welder in San Francisco, California. On July 11, 1950, Ann Ruth Zweifel married Joseph Robert Gillis in the LDS temple in Idaho Falls, Idaho. They resided for many years in Las Cruces, New Mexico and Orem, Utah, until Robert passed away on December 27, 1998.

Ann lived a life of deep commitment and courage. She leaves a noble legacy of hard work, optimism and good cheer.
