No — Ser Duncan the Tall was not a Targaryen. Nothing in any published story, history, or statement from George R.R. Martin gives him Targaryen blood: he was an orphan from Flea Bottom who never knew his parents, and the books never hint otherwise. The theory persists anyway, and the reasons it persists are actually interesting. Here is what’s known, what’s confirmed, and what’s pure fandom smoke. For the full profile, see Who Is Ser Duncan the Tall? and the interactive Targaryen family tree.
What We Actually Know About Dunk’s Origins
Almost nothing — and that’s canonical, not evasive. Dunk was a street orphan of Flea Bottom, taken on as a squire by the hedge knight Ser Arlan of Pennytree while he was still a boy. He never knew his parents or a family name, and he picked “Ser Duncan the Tall” for himself: the most literal name in the series, from a man who had nothing else to be named for.
Even the knighthood is a leap of faith. Dunk says Arlan knighted him on his deathbed, and there was nobody else there to see it. Prince Baelor vouched for him anyway at Ashford, and the story never shows anyone seriously disproving it. Baelor also told him to change the sigil on his shield, since only trueborn sons inherit arms — a pointed reminder of where Dunk stood in a world obsessed with bloodlines.
The new shield was painted by Tanselle, the Dornish puppeteer he admired. It shows a green shooting star above an elm at sunset: the sunset for Arlan, who loved them; the elm for the tree beside their camp; and the star for a lucky shooting star Dunk once saw. It’s about the least dynastic coat of arms in Westeros.
Ser Duncan the Tall at a Glance
| Detail | What the sources say |
|---|---|
| Origin | An orphan of Flea Bottom, King’s Landing’s worst slum. His parents are unknown — to the reader and to Dunk. |
| Born | Around 191–193 AC, by the usual estimate: at Ashford in 209 AC, Dunk thought he was about sixteen or seventeen. |
| Master | Ser Arlan of Pennytree, a hedge knight who took him on as a squire. Dunk says Arlan knighted him on his deathbed. |
| Name | “Ser Duncan the Tall,” which he chose himself. He has no family name. |
| Arms | A green shooting star above an elm tree at sunset, painted on his shield by the puppeteer Tanselle. |
| Later life | A Kingsguard knight by 236 AC, Lord Commander by 253 AC, and apparently lost in the Tragedy at Summerhall in 259 AC. |
So Why Does the Theory Exist?
Three reasons, and they’re understandable ones.
Secret Targaryens are this franchise’s favorite move. Jon Snow rewired everyone’s assumptions about who gets to secretly be a dragon. Once you’ve done it once, readers start checking every tall stranger’s ancestry.
Dunk keeps ending up at the center of Targaryen history. Ashford and the Trial of Seven, the Blackfyre plots, the Kingsguard, and Summerhall all run through him. Proximity to royalty reads, to some fans, like destiny — and destiny in this family usually means blood. He also spends his whole life at the side of a prince who becomes king: see Aegon V and Who Is “Egg”?.
The genuine mystery George R.R. Martin did leave. It isn’t Dunk’s parentage but where his line went, which brings us to the one confirmed connection.
The Brienne Connection (This Part Is Confirmed)
George R.R. Martin confirmed in 2016 that Brienne of Tarth descends from Ser Duncan the Tall, adding that the exact relationship would be “revealed in time.” The text plants it. In A Feast for Crows, Lord Selwyn Tarth’s armory at Evenfall Hall holds an old shield painted with Dunk’s arms, and Brienne has the design painted on her own shield. Why it ended up at Evenfall is not explained.
How exactly the line runs — through which child, and into which house — has never been spelled out. What is author-confirmed is that the connection exists. And notice which way the bloodline flows: forward from Dunk, not backward into him. The most honorable daughter of House Tarth gets that from a Flea Bottom orphan, which is the books’ quietest and best joke about bloodlines.
The Verdict
Dunk’s origin story is that he doesn’t have one — and that’s not a gap in the record, it’s the point. In a story about the weight of blood and prophecy, the greatest knight of his age comes from nowhere, knows it, and never lies about it. If you want to see how close a nobody can stand to a throne, follow him through the A Knight of the Seven Kingdoms family tree hub and read what happens next in How Dunk Became Lord Commander of the Kingsguard.
FAQ
Is Ser Duncan the Tall a secret Targaryen?
No. No book, history, or statement from George R.R. Martin gives him Targaryen ancestry. He was a Flea Bottom orphan of unknown parents, and the stories treat that rootlessness as essential to who he is.
Is Brienne of Tarth related to Dunk?
Yes. George R.R. Martin confirmed in 2016 that Brienne is Dunk’s descendant, saying the exact relationship would be revealed in time. The books hint at it through an old shield in Tarth’s armory painted with Dunk’s arms.
Who were Dunk’s parents?
Unknown — to readers and to Dunk himself. He was a street orphan taken as a squire by Ser Arlan of Pennytree, and the novellas never reveal or hint at his parentage.
Why do fans think Dunk was a Targaryen?
Because secret Targaryens are the franchise’s signature twist (Jon Snow), and because Dunk spends his life at the center of Targaryen history. But proximity isn’t parentage, and no canon source supports the theory.
Did Dunk have children?
He must have, since Brienne’s confirmed descent requires it, but no child of Dunk’s has been named in the published material.
What is on Ser Duncan the Tall’s shield?
A green shooting star above an elm tree at sunset, painted by the puppeteer Tanselle after Prince Baelor told Dunk to change the arms on Ser Arlan’s old shield.
Was Dunk really a knight?
Dunk says Ser Arlan knighted him on his deathbed, and no one else saw it. Prince Baelor vouched for him at Ashford, and Dunk spent the rest of his life acting like one — by the end as a Kingsguard knight and Lord Commander.
