That doesn't exactly help the argument, that name ("X Æ A-Xii" ) is ugly as sin and should not exist period, I pity the child that got it.
Yeah Orion is better obviously in this case, and perhaps atrocious is not the correct adjective for it, unusual doesn't cut it either but something similar or close to that. Point is that not even the greeks (contemporary ones) use that name anymore, it simply stopped being used like thousands others across history (just think latin ones you often see in roman graffiti not being used anymore) and seeing one being used in a modern setting is weird to say the least (never mind that it doesn't roll off the tongue as nicely as others), mind you that I am talking about a normal human being named that (Orion), Calypso for instance being a fantasy creature and being named that doesn't sound weird at all
