By the age of 22, Knight had completed her studies at BYA and had moved to St. George, Utah, where she was involved in family genealogical research.

Because Knight and Brimhall were the first, and for a time only, lady missionaries serving Europe, they were often asked to travel throughout England to speak.

[6] In a letter to the Deseret Evening News, missionary Joseph S. Broadbent wrote that "Sisters Jennie Brimhall and Inez Knight, both of Provo, Utah, each spoke at some length on Utah and her people and bore strong testimonies on the restoration of the Gospel and the divine mission of Joseph Smith.

Knight reported having spent "a month visiting the principal cities of France, Switzerland, Germany, Belgium, and Holland.

[6] Knight believed that one of her main purposes as a missionary was to dispel the belief, common throughout Europe, that Mormon women "were downtrodden slaves".

[9] She was named a member of the executive committee of Governor George Dern's advisory council for unemployment relief in 1931.

[2] Allen was frequently recognized and honored for her political efforts, and was named Utah's "Goddess of Liberty" at the 1898 or 1900 Provo Fourth of July Celebration.

[14] In June 1902, Knight married Robert Eugene Allen, a prominent local banker and community developer, in the Salt Lake City temple.

[16] Mr. Allen served an LDS mission in Liverpool, England, in 1905, and attended the Brigham Young Academy where he met Knight.

[22][23] Allen was the matron of the school for two years despite personal setbacks, which included falling ill with smallpox in October 1900.

[22] Allen helped initiate the community welfare department in Provo and was active in the Red Cross organization of Utah County.

[11] Her funeral was held June 9, 1937, and speakers included Dr. Franklin S. Harris, then President of BYU, and Stephen L. Richards of the Quorum of the Twelve Apostles (LDS Church).

Robert K. Allen served nationally as a U.S. Treasury agent from 1934 to 1945, working both in the United States and at the U.S. Embassy in Paris.
