Elizabeth Burnett was born circa 1798 on Goblintown Creek of the Smith River in Patrick County, Virginia, the daughter of Jeremiah Burnett (III) and Effaniah Crowley Burnett. She was married to Dabney Johnson 23 September 1813 at her father's cabin and by the time their first son, John A. Johnson, was born (29 May 1818) they had moved to the Town of Old Franklin, the county seat in Howard County, Missouri (near Independence). They spent 8 or 10 years there, then by August 1827 had moved on to Lafayette County, Missouri, later to be called Jackson County. The couple had seven more (known) children together: Jeremiah (b. 1820), Lucy (b. 1822), Elizabeth (b. 1824, married Davidson Wells), Sarah Jane "Sally" (b. 1829, married Nimrod Shepherd) Binford "Ben" (b. 1820), Thomas McBride "Tom" (b. 1831, named after a famous preacher), and Mary Ann Johnson (b. 1832-22).
After Dabney died in July 1835 without a will, Elizabeth, about age 37, continued to run the farm and administered the estate (with the help of Elisha Watkins, since Elizabeth could neither read nor write). On 9 June 1836 in Jackson County, Missouri she was married to widower Noah Nash by Thomas Nelson, a minister of the Gospel. Noah had children of his own (including a daughter Nancy, b. circa 1834?). He and Elizabeth had four known children together in Missouri: Noah Harry (b. 9 May 1837), Ann(e) (b. c. 1839), William (b. c. 1841), and Samuel (b. c. 1843).
In October 1844 Elizabeth sold her share of the Dabney Johnson farm to her son, Jeremiah Johnson, and the Nash family moved to Chariton township, Appanoose County, Iowa. The family was said to have moved to Iowa in 1845 and "first camped on the Jesse Buck farm and then... bought land across river near Walnut City." By the 1856 Iowa census, the Nash family were farmers owning 30 acres of improved land and 90 acres of unimproved land; 3 acres of spring wheat, 20 bushels harvested; 4 acres of winter wheat, 25 bushels harvested; 6 acres of oats, 75 bushels harvested; 20 acres of corn, 400 bushels harvested; had 12 hogs sold, $90 value; 1 cattle sold, $25 value; 100 pounds of butter manufactured; and 40 pounds of wool manufactured that year.
According to the 1860 U.S. census mortality schedule, Elizabeth died, age 62, of consumption (duration: 5 months) in May 1860 in Chariton township, Appanoose County, Iowa (probably at home on the Nash farm). Records or traces of her burial have not yet been found; she is not indexed in the Chariton township burial index book, but this is not unexpected for a burial that early during the days of the first pioneers of that area, among which the Nash family were numbered.
Noah Nash was listed as living with his son William and his family in Chariton Township (Centerville Post Office) in the 1870 census, age 65. He is not listed in the 1880 census, and no death or burial records have yet been found for him. Neither he nor his wife Elizabeth Burnett Johnson Nash are listed in the Appanoose County Cemetery Index published by the Appanoose County Genealogy Society in March 1990.
