I am slated to teach a college class on Michigan history this fall. As I prepare for the class, I'm reading, among many interesting things, about whether Michigan residents are properly called Michiganians or Michiganders. It's Michiganians, of course - Michigander doesn't make any sense and was originally an insult directed at Michigan politician Lewis Cass by Abraham Lincoln.
Which reminded me of the occasionally vexed question of whether to call a Stormvale member a Stormvalian or a Stormvaler. People often assume it must be Stormvalian, but it has always been Stormvaler since the early days of the branch. Why? Well, there is a degree of arbitrariness about the matter, all the more so, perhaps, because I'm probably the originator of the rule, but Stormvaler just sounded better when we first discussed this many years ago.
One might logically assume that if Michiganian, then Stormvalian, but then how does one explain New Yorker? New Yorkian just sounds goofy. Stormvalian always did, to me. So there you are.
