I know a family (Southern, white, middle-class) with boys named Fear (after a Puritan ancestor), Caedmon, Gunnar, and Owen. I always sort of pity poor Owen in that mix.
I myself have a Puritan ancestor (female) named Experience. Which strikes me as very funny to name a baby, since she obviously had none!
I have no idea what -avious means, but it clearly sounded really cool to a whole swatch of parents.
I'm changing my name to Thomasavious.
eta: Although tommyrotavious flows nicely off the tongue....
One of my favorite name encountered was Srinivaas Bophana. So pretty just floating off the tongue. Of course, his nickname was Spaz, so that kinda ruined it.
I've probably mentioned this, but my DH went to college with a woman named Lasagna. She was a twin, and I'm blanking on her sister's name (it was not unusual).
How long ago was this? Maybe she was the person who invented Lasagna!
I knew a Brame in law school. He went by his middle name, Perry.
My great-grandfather's name (and my dad's middle name) is Prosper. I think it's not entirely unusual French name.
My dad's maternal grandfather was named Prime. (The bastardization of an Italian saint name by Irish Newfoundlanders apparently.)
And my aunt was married to an Expedite. (I just don't know.)
One of my great grandfather's name was Catherinus, but googling tells me it's both a first and surname. OK.
I don't know of any weird names in my family! Some unusual, but nothing too weird. And I imagine Rolande wasn't as unusual in Quebec at the turn of the century.
