The Elk said all that needed to be said in response to the question as originally framed. Tiber Septim is not the name of a single individual with a single race. Heck, he doesn't even have a single history which combines the many entities who end up forming part of him in a single way - we're told there was a dragon break at Rimmen. The waveform is one that stubbornly refuses to be observed and collapsed.
I think the question that's really being raised here is why does Hjalti from Alcaire have such a Nordic name? And the answer seems to be: dunno, many possible reasons. There's evidence (the portrait, his birthplace, his documented lack of shouting after a fishy and convenient 'wound to the throat') that Hjalti was a Breton. However, Hjalti Early-Beard sure sounds like a Nord's name, and his Nord warrior's ghost greets him and treats him as if he were a Nord following Nordic traditions. Then there's that whole bit with the unnamed Breton nightblade who murdered the king. For those who favor the Imperial theory, well, there are the Real Barenziah books, in which he seems to look a lot like an Imperial and be treated as an Imperial.
If you're the sort who can't handle competing realities and needs to nail it down, one plausible explanation is that Alcaire, being an island, had a population of invading Nords on it, as many High Rock islands did in earlier times. Maybe Hjalti's dad was a Nord and his mother was a Breton, which would give him a Nord name and a Breton appearance.
