I'm not 100% sure why they chose 'Helena', which I hate with a passion because a) people always, ALWAYS call me 'Helen' or 'Hel-AY-na' and b) it's become kind of a yuppie middle-class twit name since then and there are about a hundred posh snots called Helena a few years below me in my school.
It could have been worse, though- they thought about calling me 'Nelly' (as in 'the Elephant', no way AT ALL that could have backfired on me during my formative years at a tough East End primary school), and if I were a boy I would have been 'Jupiter'. Yeah. You can get away with that only if you actually look like a Greek or Roman god, and the male half of my family has more of a tendency to produce skinny, spotty, speccy, pasty twits with stupid hair (my dad circa 1980 is a prime example of this). Again, there is no way I might have got the crap kicked out of me for that. Nuh-uh.
My middle names, 'Rose' and 'Rebecca', are both obscure relatives from the 19th century or thereabouts (my family is crazy obsessive about our history, and it is pretty cool in places). Rebecca in particular was pretty damn awesome, I'm pleased to be named after her, but I can't remember who Rose was. At least I'm not my sister, who is thirteen and only found out a few weeks ago how to SPELL one of her middle names (Hilary).
