-Well, I have a racist, sinister, selfish, female city elf warrior with the biggest, ugliest mace you've ever saw. She doesn't fit in any of the given backstories, she's simply too evil for that.

-A dwarf noble who've never let anything slide, every crime in his sight was punished with unstoppable force. I guess he fits the No Compromise title.
-A human noble (I know, it's lame to play a human noble in an RPG where you can be dwarf and such), he is basically the Hero of Ferelden with some hardened decisions. (Kept both Alistair and Loghain, the former sent to the throne, the latter being in my party, I'm interested to see if this particular setup is taken not of)
And've had four others, but before a system reinstall I did not make a backup of them, back then I didn't know there will be an opportunity to import.
So, as for the class-race combos, no, not really, but otherwise I do have some playthroghs which fit the backstories.
And for answering your question, my dwarf commoner is just on his way to be The Martyr. Again, the combo differs from the DA2 default backstory, but never mind.
