I picked all the options which equate to spelling the names in odd ways. It seems parents are often up in arms when someone can't pronounce or spell a child's name on the first time after giving them a different spelling
My least favorite is not up there. I don't know what it's called but someone I know has two little dots above the o in her name.
It confuses my little brain.
That is called an umlaut. It is a common symbol in some languages (including German) and denotes a different pronunciation than the letter would otherwise have. I haven't seen the umlaut used for Olivia here in Germany though
I also HATE it when people don't give twins TWIN names!! That trend kind of bugs me.
So had my children been twins I shouldn't have given them the names I liked and had picked out long ago (gosh I said if I had a boy I would name him Rio years before I had my son) because twins have to have cutesy matching names?

I see nothing wrong with "twin names" so long as they are still good as stand alone names, but I can't imagine thinking someone has to use them. Maybe they just like other names. or maybe they do not want their children to feel that their identities must always be totally intwined.
I'm sure people will think I'm a nutcase because I plan on naming my children after literary characters provided my husband is okay with it. I've always said I want my first daughter to be Ananda, a name I read in a Swiftly Tilting Planet (fourth book chronologically in the Wrinkle In Time series).
I don't think you're a nutcase at all. A Wrinkle in Time is a great book

I have a literary name and have always liked it. Hadley was the name of Ernest Hemmingway's first wife (my dad is a big Hemmingway fan). He wrote a lot about her and dedicated books to her later in his life (he "wished he had never loved another"--he was a complete jerk to her by the way but she was a pretty cool lady). My middle name is Nicole. My mom took that from the main character in Tender is the Night which was her favourite book she read in high school. I find it odd my mom chose to name me for a charcter who was insane (based heavily on Fitzgerald's real life wife Zelda), but Mom was only 19 when I was born and thought she would name me after someone "beautiful."

Anyway, I love books and reading so I love my literary names
ETA - My Joey and my Danny have been the ONLY Joey's and Danny's in their classes since they started school!! Names like Joe and Dan are now becoming 'rare'. It's weird.
The year I taught kindergarten (1994) we had five Dannys out of 24 kids

We also just moved out of a house that had 15 year old Dannys living on either side of us (and we rented to a 24 year old named Joe and one of the Danny's older brothers was also named Joey). I know, and have met, tons of Dannys and Joes in the 13-30 year old age bracket. It does seem to be tapering off now though. I guess you just happen to be where there aren't too many others in your town--lucky you (I guess, maye they want kids with the same names--my cousin always loved being one of "The Jasons"--4 in his class from K to 12

)
