Eliza Burgess was born December 8, 1927 to James and Bertha Renlock Burgess in Stockport, Chesire, England. She was the second of four children. When she was 13 years old, the family left England and sailed for the United States on a ship called the “Chaos” in Nov 1841. They arrived Jan 1842. (1)

She and her parents emigrated to Nauvoo, Illinois before the Saints began heading West.

She arrived in the Salt Lake Valley in 1849 and was married to Brigham Young on October 3, 1850. Three years later, they had a son, Alfales. He was her only child.

While Eliza and Alfales were living in the Beehive Home, she was remembered as follows:

She was still another capable, efficient housewife who loved the domestic tools and used them as skillfully as men used scythes and harrows. If Aunt Eliza Burgess ever rested, and idled away time, no one knew it. Her one release from what might have been corroding jealousy in a lesser soul was driving labor. Sewing, weaving, embroidering, cleaning, soap making, dusting, fruit drying, and every other possible pioneer art and labor provided healthy outlet for what might have otherwise cankered her wholesome spirit. For she too loved children and she bore but one son, Alfales, and him she cherished fondly. (2)

In 1869, Brigham Young bought an old colonial home in Provo. Here, he moved Eliza and Alfales. He resided in that home with them whenever he visited the area. He visited often due to his interest and involvement with ventures such as the Brigham Young Academy and the Co-operative Woolen Manufacturing Company. (3)

The year following the death of her husband, Eliza moved back to Salt Lake. She resided there until her death in 1915. “She was the last surviving wife of Brigham Young. She was a beautiful woman, a courageous pioneer and added her strength and talents to the building of the western commonwealth.” (3)
