Aurelia Read Spencer Rogers (October 4, 1834 – August 19, 1922) was the founder of Primary, the children's organization and official auxiliary of The Church of Jesus Christ of Latter-day Saints. Rogers was also a women's rights activist and suffragette.
Aurelia Read Spencer was born at Deep River, Middlesex County, Connecticut, the eldest child of Orson Spencer and Catherine Cannon Curtis. When Aurelia was 12 years old, her mother died at Sugar Creek, Iowa. A few months later, her father was asked by Brigham Young to become the new mission president for the church in Europe. As the second eldest child, Aurelia and her elder sister were made responsible for assisting the other four siblings in the move to the Salt Lake Valley, which the Spencer children completed in 1848. Orson Spencer returned from Europe in September 1849 and joined the family in Salt Lake City.
On March 27, 1851, Aurelia married Thomas Rogers in Salt Lake City. The Rogers moved to Farmington, Utah Territory, where Rogers would raise ten children.
In 1878, Rogers had become concerned that younger Latter-day Saint children had too much unsupervised time. In particular, Rogers felt that the younger boys in the community were becoming unruly and mischievous. While praying for guidance, Rogers said she heard a voice say "that there was an auxiliary organization [in the church] for all ages except the children".
