This really has nothing to do with anything, but sometimes I come across random stuff that I find interesting. I love names. I always like to know the whole names of the kids. I like knowing why they got named that and who it honored and how it got chosen. It's just fun stuff. Even though I don't plan to have more kids of my own, I still think about what I would name them if I did.
I think this Swedish study is interesting. We don't have any boys here who end in -y. I do tend to notice that a lot of little boys go by the y-nickname and then change it as they get older. Joey to Joe or Joseph, Nicky to Nick or Nicholas. That kind of thing. And I do know a grownup Billy who doesn't seem to be a criminal. :) y-names do make me think of Italian mobsters sometimes though.
Another study I read years ago has stayed on my brain. I can't find a link to it, but basically it said that moms with lower education levels tended to name their babies after expensive objects- stuff like Crystal, Porsche, and Jade. Moms who were college-educated trended names that ended in -n.
On our current roster we have no expensive object babies. However, Duchess, Tod, Copper, Alice, Tarzan, Hercules, Tigger, Roo, Lady, and Mater all end in -n. I'd say the theory works well in our case.
*of course, there are MANY lovely and educated names that just don't end in N. That's what the rest of our kiddos are. Don't be thinking that I'm trying to hate on your education level. Just mulling on a study.....
