The Greystone Bastard (naming lore query)

[Anonymoose]

I was kind of surprised to see so much resistance to the idea that it was a bastard surname (to the point that, hey, maybe he had two battle titles and they nixed the surname on his public memorial in favor of the less popular one).

It's a core feature of Haurchefant's character that the most chivalrous member of House Fortemps was supposedly beneath its name. It's almost more offensive to raise him up after he's dead, isn't it? Treating him like he earned an upgraded name when in truth he humbled those who bear it? When it comes to what goes down in history, Haurchefant Greystone is an example that I wouldn't want diluted by a posthumous feel-good gesture.

If in-world logic isn't enough, though, let's come out-of-world for a minute.
Haurchefant needed a quick-but-meaningful backstory and they invoked Jon Snow.
