Right sorry for the wait dear fellows, here is what I have managed to drag up from the legends so far, and it appears to be one tangled web:
There were 4 Dwarves (not 5 as I mistakenly claimed earlier) who obtained titles in the late winter of 452:
Niri Peltsmiths - baroness of Portentguilds (only noble actually killed during the riot, real bummer for the save copies in which I'm continuing the fort post civil war).
Doren Fortresswashed - count of Pureinks
Asen Blockedwhisper baroness of Lobsterstockade
Likot Bronzespears - baroness of Sprinkledrazors
Portentguilds is a hillocks, history mostly comprised of stuff getting stolen, Kidnapping and Roc attacks.
Pureinks is a Fortress, in late winter 452 - about the time of the Succession Riots - it was attacked by Goblins who secured tribute.
Lobsterstockade is a hillocks, again kidnappings, roc attacks, etc. Recorded history ends a few years before the event.
Sprinkledrazors - Fortress, history seems largely uneventful and stops recording the year before.
It turns out Doren is Likot's Father, and her mother was a Werewombat that was killed in the mid winter of 452 by my militia.
What looks to have happened, is that Niri's Mother was made a Baroness then moved to Pureinks, where Doren's Father was already count and Asen's mother was also a baroness.
The trio were all killed in the 452 gobbo raid.
