Abraham Lincoln’s family tree reflects a rich tapestry of humble American origins, westward migration, political ambition, and profound personal tragedy. While the 16th President of the United States rose from a log cabin to the highest office in the land, his lineage is characterized by early American pioneers, industrious farmers, and a tragic extinction of his direct bloodline by the late 20th century. Understanding the Lincoln genealogy requires examining both his ancestral roots stretching back to England and New England, and the famous family he built with Mary Todd Lincoln.
The Ancestral Roots: From England to the American Frontier
The American Lincoln lineage began with Samuel Lincoln, who crossed the Atlantic Ocean from Hingham, Norfolk, England, arriving in Massachusetts in 1637 as a young apprentice weaver. Samuel settled in Hingham, Massachusetts, establishing the family's presence in the New World. From Massachusetts, the family steadily migrated southward and westward through New Jersey, Pennsylvania, and Virginia, reflecting the broader patterns of early American colonial expansion.
Abraham Lincoln’s grandfather, also named Abraham Lincoln, moved the family from Virginia into the Kentucky frontier during the late 18th century. In 1786, tragedy struck when this elder Abraham Lincoln was killed by a Native American raiding party while working his fields. His young children, including nine-year-old Thomas Lincoln (the future president's father), witnessed the event. This frontier violence left Thomas Lincoln to grow up with little formal education, struggling as a migratory laborer and farmer in Kentucky and Indiana.
Thomas Lincoln and Nancy Hanks: The Parents
Thomas Lincoln (1778–1851) married Nancy Hanks (1784–1818) on June 12, 2006—historically corrected to June 12, 1806, in Washington County, Kentucky. Thomas was known as a strong, industrious man skilled in carpentry and farming, though he never achieved significant financial prosperity. Nancy Hanks was a woman of humble origins and quiet resilience.
Together, Thomas and Nancy had three children:
- Sarah Lincoln (1807–1828): Abraham’s older sister, who married Aaron Grigsby in 1826 and tragically died during childbirth at age 21, along with her infant son.
- Abraham Lincoln (1809–1865): The 16th U.S. President.
- Thomas "Tad" Lincoln Jr. (born and died in 1812): An infant who died shortly after birth in Kentucky.
Following Nancy Hanks Lincoln's death from milk sickness in 1818 in Spencer County, Indiana, Thomas Lincoln traveled back to Kentucky to court Sarah "Sally" Bush Johnston, a widow with three children of her own. They married in December 1819. Sally Bush Lincoln proved to be a deeply loving stepmother who recognized young Abraham's intellect, encouraging his love for reading and learning despite his father's preference for manual farm labor.
Marriage to Mary Todd and the Immediate Family
On November 4, 1842, Abraham Lincoln married Mary Todd (1818–1882) in Springfield, Illinois. Mary Todd came from a prominent, wealthy slave-owning family in Lexington, Kentucky, representing a stark contrast to Lincoln's impoverished upbringing. Despite their differing backgrounds, political ambitions, and distinct personalities, the couple shared a complex, enduring partnership marked by deep affection and shared grief.
| Child Name | Birth Year | Death Year | Life Details |
|---|---|---|---|
| Robert Todd Lincoln | 1843 | 1926 | Only son to survive to adulthood; lawyer, businessman, and Secretary of War. |
| Edward Baker Lincoln | 1846 | 1850 | Died in Springfield, Illinois, likely of pulmonary tuberculosis. |
| William Wallace Lincoln | 1850 | 1862 | Died of typhoid fever in the White House during his father's presidency. |
| Thomas "Tad" Lincoln III | 1853 | 1871 | Died in Chicago at age 18 from heart failure or pleurisy. |
The Tragic Fates of the Lincoln Sons
The Lincoln household was shadowed by immense parental grief. Of their four sons, three died before reaching adulthood:
- Eddie Lincoln died just a month shy of his fourth birthday in 1850. His death devastated Abraham and Mary, inspiring poems and reflecting their early experiences with child loss.
- Willie Lincoln died in the White House in February 1862 at the age of eleven. His passing plunged both parents into deep mourning during the height of the American Civil War.
- Tad Lincoln survived his father's assassination, traveling with his mother to Europe before returning to Chicago, where he died at age 18 in 1871.
The Sole Surviving Son: Robert Todd Lincoln
Robert Todd Lincoln was the only child of Abraham and Mary Lincoln to survive into adulthood and have children of his own. Born in Springfield, Illinois, Robert attended Phillips Exeter Academy and graduated from Harvard College. He served briefly on the staff of General Ulysses S. Grant during the final months of the Civil War.
Following his father's assassination in April 1865, Robert pursued a highly successful career. He served as the U.S. Secretary of War under Presidents James A. Garfield and Chester A. Arthur, and later as the U.S. Ambassador to the United Kingdom. He also became a wealthy corporate lawyer and president of the Pullman Palace Car Company.
Robert married Mary Eunice Harlan (1846–1937) in 1868. They had three children, bringing grandchildren into the Lincoln family tree:
- Mary Lincoln (1869–1938), who married Charles Isham.
- Abraham Lincoln II ("Jack") (1873–1890), who died in London of blood poisoning following an infected cyst.
- Jessie Harlan Lincoln (1875–1948), who married three times and had two children.
The Extinction of the Direct Lincoln Bloodline
The direct biological line of Abraham Lincoln came to an end in the 20th century. Robert Todd Lincoln’s only son, Abraham Lincoln II, died childless in 1890 at age 16. Robert's daughter Mary Lincoln Isham had one son, Lincoln Isham (1892–1971), who had no children.
Robert's other daughter, Jessie Harlan Lincoln, had two children: Mary Lincoln Beckwith (1898–1975) and Robert Todd Lincoln Beckwith (1904–1985). Neither of Jessie's children had children of their own.
When Robert Todd Lincoln Beckwith died in 1985 without issue, he was the last known living descendant of Abraham Lincoln, bringing a complete end to the president's direct biological descendants.
Collateral Relatives: The Extended Hanks and Lincoln Families
While Abraham Lincoln’s direct lineage has ended, his extended family tree remains vast through his paternal uncles, aunts, and maternal relatives. Thousands of collateral descendants exist today through the Hanks family and the broader Lincoln family network, which spans across multiple states including Kentucky, Indiana, Illinois, and beyond. Genealogists and historical societies continuously map these lateral branches, connecting modern citizens to the extended kin of America's 16th president.

Next Steps for Genealogical Research
For individuals interested in exploring historical genealogy or tracing early American pioneer families, consulting primary documents such as federal census records, military service records, and state vital statistics in Kentucky, Indiana, and Illinois offers authenticated proof. Local historical societies and presidential libraries, such as the Abraham Lincoln Presidential Library and Museum in Springfield, Illinois, provide extensive archives for researchers examining 19th-century American lineages.
