The Importance of Birth Order

This is a rather odd hypothesis, and I'm not even sure that I have formed it fully, but this is the sort of thing that I get idly musing about. Does your own order of birth have any connection with your preferences in favorite characters?

I'm the second oldest in my family. And it occured to me, with something of a slight shock, that a great number of my favorite characters are ALSO the second children.

Hal Jordan for example. He's a middle child, with an older and younger brother, and the older one, was something of a bully.

Guy Gardner is a second child, and we all know how WONDerful Mace Gardner was. Mr. Golden Boy, and also something of a bully.

Jack Knight is a cool character, and lo and behold, his older brother David was occasionally a douchebag and a bully too.

Heck, even Wolverine had a creepy older brother.

There do seem to be a lot of only children out there, Wonder Woman, Superman, Batman, Nightwing, Green Arrow, Black Canary, Flash(Wally anyway), Aquaman, Kyle Rayner, Capt. America, presumably Hawkman, Barbara Gordon, Ted Kord, and probably a ton more.

It's rather nice I think, when superheroes have siblings. Jaime Reyes is actually the oldest, but at least he has Milagro. Booster Gold has Michelle. Even J'onn J'onnz had an evil brother.

And then there's the orphans. Man oh man, are there a lot of orphans. I think that it may be easier to name the superheroes that HAD a two-parent household growing up than the number of orphans, or at least single or widowed parents.

Jaime Reyes heads that list, he has some of the most awesome parents around. Also high on that list are Jonathan and Martha Kent. Bats may be an orphan, but at least he had good and loving parents for a little while. Guy had two parents, although I'm doubtful about the good and loving part. Still...they were at least there. Hal had two for a while, and as much as his mother can annoy me, she did her best to raise three boys on her own.

There were a number of fathers that deserted the families, such as Booster's and Kyle's. I can't think of too many where the mother deserted, although there are a bunch where the mom died. So, I suppose, in a way, that superhero families are pretty much like the rest of the general population's, not at ALL typical. I've rather lost the gist of my original thought however. Do any of you find that you are skewed towards liking a particular character in relation to your own birth order? Do orphans drift towards Batman and Robin? Adopted aliens just naturally like Superman? Single offspring like Tim Drake?

Or am I just blowing smoke?
