An unknown amount of time after Whitewalls, Duncan and Aegon visited [[Winterfell]].<ref>[[Not a Blog]]: ''[https://georgerrmartin.com/notablog/2014/04/15/dunk-and-egg/ Dunk and Egg]'' (April 15, 2014)</ref>

Presumably in honor of Ser Duncan, Prince [[Aegon V Targaryen|Aegon Targaryen]] named his firstborn son and heir [[Duncan Targaryen|Duncan]] (however, when asked about it, [[George R. R. Martin]] refused to answer).{{Ref|SSM|1105}} Prince Duncan was called "Duncan the Small".{{Ref|ASOS|67}}

Both he and Aegon had some involvement during the [[Peake Uprising]], where Aegon's father was killed.<ref>[[So Spake Martin]]: [http://www.westeros.org/Citadel/SSM/Entry/Chicon_7_Reading Chicon 7 Reading (September 2, 2012)]</ref>

In late {{Date|233}}, after Aegon had ascended the throne as [[Aegon V Targaryen]], Duncan escorted the king's brother, Maester [[Aemon Targaryen (son of Maekar I)|Aemon]], to [[Eastwatch-by-the-Sea]], where Aemon was going to join the [[Night's Watch]].{{Ref|AFFC|15}}

Duncan eventually joined the [[Kingsguard]]. While it is unknown when exactly he took his vows, the first known mention of him as a Kingsguard knight is in {{Date|236}}.{{Ref|TWOIAF|4|15}}

In {{Date|236}}, Ser Duncan fought in the [[Fourth Blackfyre Rebellion]] and personally slew [[Daemon III Blackfyre]], the [[House Blackfyre|Blackfyre Pretender]].{{Ref|TWOIAF|4|15}}

In {{Date|239}}, when Prince [[Duncan Targaryen]] broke his betrothal to Lord [[Lyonel Baratheon]]'s daughter and married a commonborn girl known as [[Jenny of Oldstones]] instead, the enraged Lyonel renounced his fealty to the [[Iron Throne]]. Duncan served as King Aegon V's champion in the [[trial by combat]], in which he bested Lyonel, thereby ending his short rebellion.{{Ref|TWOIAF|4|15}}{{Ref|TWOIAF|7|8|4}}

In {{Date|253}}{{Ref|AWOIAF|Duncan}} Duncan, by then [[Lord Commander of the Kingsguard]], participated in a [[winter tourney at King's Landing]], where he was defeated by a sixteen-year-old [[Barristan Selmy]].{{Ref|ASOS|67}}

In {{Date|259}}, Duncan apparently perished in the [[tragedy of Summerhall]],  along with King Aegon V and Prince Duncan, among others.{{Ref|AWOIAF|Duncan}}{{Ref|TWOIAF|4|15}} Little is known about the events of the tragedy, but it seems that the Lord Commander's valor saved some of the survivors from dying in the great fire that consumed [[Summerhall]].{{Ref|TWOIAF|4|15}}
