I knew a Thor and Aristotle growing up, as well as a steady stream of boys with modern girls-names-that-were-once-English-boys-names, and umm, a bunch of other interesting ones I now forget. I grew up in Lexington, MA, which is pretty bougie, and these were all the children of first generation immigrants.
I knew an Obediah, and have a nephew named Thor. He was a high spirited child. His grandmother called him “Thorn”.
I knew one years ago. She would be in her early 60s now, I think. However, I think she spelled it something like Rhoen.
Oh, and I have just remembered a girl I used to know who was called something like Armanil (IIRC, which I may not, but it was something weird like that).
This isn’t so strange compared to others, but I went to day care with a girl named August. It was only later that I found out that that was generally a masculine name, and now I wonder what the source of her name was. I know for a fact she wasn’t born in August.
I thought of this thread today when I got an e-mail at work with one of the several men named Os(s)ama at our facility. We have a fairly large number of folks from the ME there, with names that are common in their home countries.
I know a Ptolemy.
Went to grade school with a Sage (female) and to Middle and HS with a Kiant. (male)
I have an ex-boyfriend named Don-Juan, so there. He has a BUNCH of siblings by a BUNCH of different moms, all named variations of his dad’s name (Donald).
His mom has two other children (who are much older than Don and have a different father) with extremely classic, respectable names, and she’s a classy woman who I like better than her son. Donald has little to do with many, if not all of his kids, but somehow convinced about six moms to name them after him. I’ve never met the man, but out of curiosity I would kind of like to. If I didn’t know Don-Juan’s mom, I’d think okay, they’re just stupid, but she’s not that way at all.
This might sound weird to you because it’s a foreign name, but to me it sounds even weirder as a first name. It means “Hoe” - the gardening tool. It’s used as a surname in Sicily, but as a first name? Hoe Smith?
When I lived in Italy I met people with badly mangled versions of English names, usually spelled phonetically. So there were a Gionni (Johnny) and a Lusi (Lucy) that were customers of my dad, and another woman in the next town over named her baby boy Geiar, this from the bad guy in Dallas, the 80s soap opera, J. R. Ewing.
I don’t think Benedict is that uncommon in the UK as to be remarkable. When I was an undergraduate one of my classmates was called Benedict.
A neighbor’s young son is Strayhorn, named after the surname of Duke Ellington’s collaborator.
A colleague is called Eon, because his father thought that was how to spell it. I think he meant **Eóin **which I believe is the original form of Ian.
A friend of the family named her daughter McKenzie, which caused a bit of a stir at the time.
My Dad’s name was Royal, and was always called such, never ‘Roy’'. He was born in 1920 fwiw.
My BIL’s name is Byron. Middle name Jeremiah. He’s a fantastic guy, but not nearly as grand as his name sounds 
At the barn where I used to teach riding I knew a girl named Meadow, and then later a girl named England and her little brother Paris. Yes, those were all conception names.
The BBC web site had a piece about the name Benedict (after Pope Benedict retired).
I know a young British woman named Tuppence.
In middle school, one of my classmates was a girl named Xerxes. Not after the Persian king; supposedly it was the name of a wise woman from Atlantas.
In college, I was in the band with a Kunegunda, which is apparently a not-uncommon Polish name. She said that most American Kunegundas go by “Candy”, but she enjoyed her unusual name.
Also in college, I occasionally ran into an Arwen, named after the Lord of the Rings character. She was very surprised when I knew the origin of her name (this was well before the movies).
And I have a cousin-once-removed named Odin. I think it must come from his mother’s family-- There’s no Norse heritage in ours.
Personally, I favor the tactic someone mentioned on the first page of giving kids ordinary first names but exotic middle names that they can choose to use or ignore.
