People usually think of Abraham Lincoln as a solitary figure. You've seen the photos—the tall, gaunt man sitting alone in a chair, or the bearded face on the penny. It’s easy to imagine he just sort of sprouted from the Kentucky soil fully formed. But honestly, the "Self-Made Man" trope only goes so far. Lincoln had a family. He had siblings. And if you've ever wondered did Abraham Lincoln have brothers and sisters, the answer is yes, but it’s a story defined more by loss than by long-term companionship.
History is a messy thing. It’s not just dates and battles; it’s about who sat next to you at the dinner table when there wasn't enough food to go around. For Abe, that was his older sister, Sarah, and for a very brief, tragic moment, a younger brother named Thomas.
The Sister Who Raised Him: Sarah Lincoln Grigsby
If you want to understand the man who became the 16th President, you have to look at Sarah. She was born in 1807, making her about two years older than Abraham. In the rough-and-tumble world of early 19th-century Kentucky and Indiana, an older sister wasn't just a sibling. She was basically a second mother.
Sarah and Abraham were incredibly close. They walked miles together to reach those tiny, one-room "blab schools" where they learned their ABCs. Think about that for a second. Two kids, wandering through the dense woods of the frontier, clutching a few scraps of paper or a slate. It wasn't romantic. It was hard.
When their mother, Nancy Hanks Lincoln, died from "milk sickness" in 1818, the world fell apart for the Lincoln children. Abraham was only nine. Sarah was eleven. Can you imagine an eleven-year-old girl suddenly being responsible for the cooking, the cleaning, and the emotional well-being of her father and brother in a dirt-floor cabin? That’s exactly what happened. She stepped up because there was no other choice.
A Heartbreaking End
Sarah eventually married a man named Aaron Grigsby in 1826. But the tragedy that seemed to follow the Lincolns didn't stop there. Just two years after her marriage, Sarah died while giving birth to her first child. The baby didn't survive either.
Abraham was devastated. Neighbors later recalled that when he heard the news, he sat down and wept for hours. Some historians, like Joshua Wolf Shenk, who wrote Lincoln's Melancholy, suggest that these early losses—first his mother, then his sister—were the seeds of the deep, clinical depression that haunted Lincoln his entire adult life. He didn't just lose a sister; he lost his primary connection to his childhood.
The "Forgotten" Brother: Thomas Lincoln Jr.
Most people asking did Abraham Lincoln have brothers and sisters are surprised to hear there was a third child. His name was Thomas Lincoln Jr., named after their father.
He was born in 1812, while the family was still living at Knob Creek Farm in Kentucky. He didn't live long. In fact, he died in infancy. We don't even have an exact date for his death, just that it happened shortly after he was born.

In those days, infant mortality was a brutal reality of life. You didn't get a big headstone or a long obituary in the paper. You got a small grave on the property. For a long time, the location of his grave was lost to history. It wasn't until the mid-20th century that researchers identified a small, rough-hewn stone in the Redmon family cemetery in Larue County, Kentucky, as the likely resting place of little "Tommy" Lincoln.
Abraham rarely spoke about his younger brother. Is that because he didn't remember him, or because the memory was too painful? Probably a bit of both. But that loss added another layer of "quiet" to the Lincoln household.
The Step-Siblings: A New Family Dynamic
By 1819, Thomas Lincoln (the father) realized he couldn't run a frontier farm and raise two kids alone. He went back to Kentucky and found Sarah Bush Johnston, a widow with three children of her own. He married her and brought her back to Indiana.
Suddenly, the cabin was crowded. Abraham and Sarah now had three step-siblings:
- Elizabeth Johnston
- Matilda Johnston
- John D. Johnston
This changed everything. Sarah Bush Johnston was a godsend for Abraham. She noticed his intellect and encouraged him to read, even when his father thought he was being "lazy" by sticking his nose in a book. While Abraham wasn't particularly close to his step-sisters in the long run, his relationship with his step-brother, John D. Johnston, was... complicated.
The Trouble with John D. Johnston
John was the opposite of Abraham. While Abe was ambitious and intellectually curious, John was often seen as a bit of a "drifter" or a "slacker."
Even after Abraham moved away to New Salem and eventually Springfield to practice law, John kept writing to him asking for money. We actually have some of the letters Lincoln wrote back. They are fascinating. In one letter from 1851, Lincoln basically gives him a stern "tough love" lecture, telling him that he won't send money because it would only encourage John's idleness. He told him to get a job and work for his keep, just like everyone else.
Despite the friction, they were family. They shared a roof during those formative, lean years in Indiana. They survived the "starving times" together. You can't just erase that history.

Why Does This Matter?
You might think, "Okay, so he had a sister who died young and a brother he never knew. So what?"
It matters because it shapes the man. When you look at Lincoln’s empathy—his ability to feel the weight of a nation’s grief during the Civil War—that didn't come from nowhere. It came from a boy who had to help his father whip out a coffin for his own mother. It came from a young man who saw his only sister buried in the woods because medical care was non-existent.
When people ask did Abraham Lincoln have brothers and sisters, they are really asking about the forces that made him.
Lincoln's life was a series of subtractions.
1812: Brother dies.
1818: Mother dies.
1828: Sister dies.
By the time he was 19, his biological nuclear family was almost entirely gone, except for a father he had a very strained relationship with. This isolation drove him toward books, toward the law, and toward a desperate need to find a "new" family in the American public.
The Impact of Frontier Life on the Lincoln Siblings
Life on the frontier wasn't like Little House on the Prairie. It was filthy. It was dangerous. The "milk sickness" that killed his mother was actually caused by drinking milk from cows that had eaten the white snakeroot plant. People didn't know that then. They just thought it was a curse or "bad air."
Sarah Lincoln would have been the one milking those cows. She would have been the one cleaning the sores of the sick. The burden placed on siblings in these environments was immense.
Abraham’s physical strength, often noted by his contemporaries, was built alongside his siblings and step-siblings. They cleared land together. They split rails together. That shared physical labor creates a bond, even if the emotional connection is frayed by later life choices or distance.

The Grigsby Feud
The death of Sarah Lincoln also sparked a weird, bitter feud between Abraham and the Grigsby family (his sister's in-laws). Abe blamed them for not calling a doctor soon enough when Sarah was in labor.
He didn't just stay quiet about it, either. He wrote satirical poems and "chronicles" mocking the Grigsbys. It was a petty, human side of the man we rarely see in history books. It shows just how much he hurt over the loss of his sister. He wasn't just a stoic statue; he was a grieving brother who lashed out.
Key Facts About the Lincoln Siblings
To keep things clear, here is the breakdown of who was who in that crowded Indiana cabin:
- Sarah Lincoln (1807–1828): The older sister. His closest childhood confidante. Died in childbirth.
- Thomas Lincoln Jr. (1812): The infant brother. Lived only a few days or weeks.
- Elizabeth Johnston: Step-sister. Mostly stayed out of the historical record after marriage.
- Matilda Johnston: Step-sister. Abraham was reportedly fond of her; she once snuck up on him while he was chopping wood, causing an accident that stayed in his memory.
- John D. Johnston: Step-brother. The "black sheep" who frequently asked for loans.
Finding the Lincoln Legacy
If you want to see where this history happened, you can actually visit these sites. The Lincoln Boyhood National Memorial in Lincoln City, Indiana, is where the family lived when Sarah died. You can walk the woods they walked. It's quiet there. You get a sense of the loneliness they must have felt.
The grave of Sarah Lincoln Grigsby is still there, in the cemetery of the Little Pigeon Baptist Church. It’s a sobering reminder that while Abraham went on to change the world, his sister stayed behind in the Indiana soil, a casualty of the hard life they both endured.
Actionable Steps for History Buffs
If you're digging into Lincoln's family tree, don't just stick to the famous biographies.
- Check out the Primary Sources: Read Lincoln’s 1851 letter to John D. Johnston. It’s easily found in the "Collected Works of Abraham Lincoln." It gives you a raw look at his family dynamics that no historian can replicate.
- Visit the Sites: If you’re ever in Kentucky or Indiana, skip the big city museums for a day. Go to Knob Creek. Go to the Lincoln Boyhood Home. Stand in the footprints of these kids.
- Look at the Women: Most of what we know about Sarah Lincoln comes from neighbors interviewed by William Herndon (Lincoln’s law partner) after the assassination. Look into the Herndon's Informants collection for the real, unvarnished stories of the Lincoln siblings.
- Understand the "Milk Sickness": If you’re interested in the health aspect, research the Ageratina altissima plant. Understanding the science of what killed his family makes the tragedy feel much more real and less like a "long time ago" story.
Abraham Lincoln was many things: a lawyer, a politician, a writer, a savior of the Union. But before all that, he was a little boy in a cabin, trying to keep up with his older sister and wondering why his baby brother didn't get to stay. That human element is what makes his story stick. He wasn't just a figure from a textbook; he was a brother who knew exactly what it felt like to have his heart broken by the people he loved most.
