I think the assumed average age for getting your Aura unlocked is 13, the age of anyone entering a Signal-level academy (basically, pre-Beacon school). Or so we've assumed. So really, unless his brother died before he turned thirteen, with a back story like the one you wrote his Aura wouldn't be unlocked until he was thirteen, when everyone else got their's unlocked at school. Unless his brother died before he was thirteen, in which case it's acceptable as long as you don't make him too young (I think nine is the minimum decont age in this case).
