I wasn't all that fond of my name to begin with. I originally thought it was because the full thing only comes out when I was in trouble, lol. At some point in elementary school I had a class with three other kids who had similar names, and I ended up answering to one of them instead of mine, lol. They had a name I wanted more than the one I started with. Fortunately, they both shorten to the same thing, so I kinda just stole that person's name without telling anyone. My full name comes out so rarely that it doesn't make a difference.
On the other hand, I spend so much time online that I never use my name anyways. Even online, I rarely use the same username across different games or sites, just the numbers at the end. I don't really think of 396 as a name, more a signature... So in reality, I kinda don't have a name? And I don't feel bad about that at all. ?
To the second question, I was originally named after one of my parent's siblings, but I never met them or heard any stories about them other than 'Oh, that's who you were named after.' Kinda boring, huh?
[I pick character names by googling meaningful names that seem to relate to the character. At least, when I want real world names. I've always been fond of word salad type names I made up based on LotR or DnD. Shynwaelin is a standout example.]
