Jane Randolph Jefferson, née Jane Randolph (February 9, 1720 – March 31, 1776) was the wife of Peter Jefferson and the mother of president Thomas Jefferson. Born in Shadwell Parish, Tower Hamlets, London, she was the daughter of Isham Randolph and Jane Rogers, and a cousin of Peyton Randolph..
Early life and education
Randolph was born in one of the Tower Hamlets, Shadwell, a poor maritime neighborhood of London. She most likely immigrated to Virginia as a child with her family and that her education was received entirely at home. Little is known of her, for Jefferson rarely mentioned his mother in his extensive writings. According to the 20th-century biographer Merrill Peterson, she represented "zero quantity" in her son Thomas's life, although more recent scholarship questions Peterson's conclusions..
Marriage and family
Randolph married Peter Jefferson in Virginia in 1739. Together, they had the following children:
Jane Jefferson (1740–1765) - close to her brother Thomas, she died unmarried at age 25.
Mary Jefferson Bolling (1741–1811) - her husband John Bolling served in the Virginia House of Burgesses.
Thomas Jefferson (1743–1826), third President of the United States
Elizabeth Jefferson (1744–1774) - mentally handicapped
Martha Jefferson Carr (1746–1811) - her husband Dabney Carr, Thomas Jefferson's best friend, helped launch the intercolonial Committee of Correspondence in Virginia in March 1773, the first step to coordinated colonial action against Great Britain.
Peter Field Jefferson (1748)
Unnamed Son (1750)
Lucy Jefferson Lewis (1752–1810)
Anna Scott Jefferson Marks (1755–1828) - twin of Randolph
Randolph Jefferson (1755–1815) - twin of Anna Scott
Jane Randolph Jefferson died from what was described at the time as an "apoplexy" on March 31, 1776, barely three months before Jefferson wrote the Declaration of Independence..
↑ Some discrepancy on birthdate. Thomas Jefferson recorded February 9, 1720 in his Prayer Book (housed at Univeristy of Virginia Library). However, according to chancery information published in the Virginia Magazine of History and Biography 26, no. 3 (1918): 324, Jane was baptized on February 20, 1720, and was 15 days old at the time.

It may be possible to confirm family relationships with Jane by comparing test results with other carriers of her mitochondrial DNA.
However, there are no known mtDNA test-takers in her direct maternal line.
It is likely that these autosomal DNA test-takers will share DNA with Jane:
