Minor nitpick, but this feels like one of those moments where Paolini didn’t lean much on historical models. Murtagh is a highborn noble raised at court. He should know better than to call his new dynasty “House Murtagh.”
If a man named Edward stood up in the Middle Ages and declared himself head of “House Edward,” it would sound bizarre and off.
“House X” names usually weren’t formal titles used at the time. They’re labels applied later by others, based on how medieval naming actually worked. Prestige also came from age, so naming a house after yourself basically advertises that it’s brand new, which is social suicide among old-money nobility.
“House Murtagh” reads like: I have no ancestors worth citing, so I’m using myself. Other lords would see it as vanity at best, social ignorance at worst: “Look at this peasant, he thinks he’s his own ancestor.”
In the medieval mindset, a house isn’t just you. It’s the dead, the living, and the unborn. You belong to a house; you aren’t the house. Naming it after your own first name while you’re still alive muddies that distinction. It’s like King Charles III renaming the House of Windsor to “House Charles.” The system doesn’t work like that.
Families were usually tied to places or long-standing identifiers, like Plantagenet (from planta genista, the broom plant), House of Habsburg (from Habsburg Castle), or Tudor (from the Welsh name Tudur). Even labels like “Ottonian” or “Carolingian” came later. Otto I didn’t think of himself as “Ottonian”; he was Saxon, of the Liudolfing line. “Ottonian” is a label applied to his dynasty after the fact.
It wasn’t typical to invent a house name on the spot. A savvy climber (as one would expect Murtagh to be) would anchor himself to the oldest ancestor he could claim, or to land with history. He could almost certainly trace his lineage beyond Morzan. His upbringing in the capital would have drilled lineage into him.
The one exception might be heraldry. If Murtagh used a personal symbol, people might associate his line with it, but he still wouldn’t formally style it “House Murtagh.”
A good comparison is Raymun Fossoway from A Knight of the Seven Kingdoms. He wants to distinguish himself from the Red Apple Fossoways, but he doesn’t create “House Raymun.” He founds a cadet branch, changes his sigil to a Green Apple, and remains a Fossoway. Over time, they become the Green Apple Fossoways or House Fossoway of New Barrel, but “Fossoway” remains the anchor.
So “House Murtagh” sounds weird. It also clashes with his goal of distancing himself from Morzan. In a medieval context, inventing a brand-new identity looks suspicious, like insecurity or social climbing.
More likely, he’d anchor himself to land. If Morzan was famously tied to something tainted (say “Morzan of Black-Mire”) Murtagh would abandon it and establish a new seat. He’d become “Murtagh of Fairhaven,” and his descendants would take identity from that place. This kind of reset was common, especially after the Norman Conquest.
If he wanted stronger legitimacy, he could reach further back. His mother has distant ties to older royal lines like Palancar, which is far more valuable than starting from scratch. He could claim he is the Restorer of the House of Palancar. Even a thin ancestral claim is better than none.
He could also lean into reputation. A defining act could organically evolve into a family identity over time as with Shadeslayer or Stronghammer.
Or symbolism. Thorn is the obvious anchor. A red dragon or thorn sigil, or a stronghold named after Thorn, could lead to something like “House Thorn/of Thorn” over generations, which is far more organic than naming it after himself outright.
There’s also a practical issue of inheritance. Medieval legitimacy runs on continuity. Declaring a brand-new house risks severing claims to his father’s lands, titles, or rights (even the ones that weren't "evil"). His attachment to Zar’roc as the "only thing he expected to receive as inheritance," and his resentment toward Brom for "stealing" it from his father, show that inheritance still matters to him.
All of this makes Murtagh feel less like the cunning, educated noble he’s meant to be portrayed as, and more like Paolini using a modern fantasy shorthand. It communicates the idea quickly, but doesn’t align with the social logic the story otherwise uses.
Especially since other noble lines in the series follow more historical patterns. Orrin is of the House of Langfeld, which was named after a victory or place, not its founder Lady Marelda. Thanebrand the Ring Giver follows the same reputational logic as Roran Stronghammer. The Earls of Fenmark are tied to a long-standing territorial identity.
The only real historical parallel I can think of to "House Murtagh" is the House of Osman, but that emerged from a nomadic system where identity was tied to a leader rather than an inherited house (Osmanlı = “those who follow Osman”). That’s fundamentally different from the sedentary, lineage-obsessed nobility Murtagh was raised in.
Using that model would make him a warlord or chieftain, and not a duke or lord within the Broddring system.
