What's the name of High King Borogrim the Hale

[Hikarizu]

https://pathfinderwiki.com/wiki/Borogrim.
Is Borogrim his first or last name, and what is the other one? Can't find it online.

I found him referenced as Borogrim Ironfist on some campaign journal on the obsidianportal. Can someone confirm or deny this?

Borogrim is probably his first name. Traditionally many kings have only gone by a first name in part because it's expected that most of the kings will be from the same dynasty and thus would have the same surname (assuming the dynasty even has a surname.) Some royal houses don't have last names so it's possible he doesn't have a surname. It's also possible he does and the lore just doesn't mention it.
