There's a well-studied phenomenon called "social diffusion". People of higher socioeconomic status seek out novel, unique, or fashionable baby names and start using them. These names gradually get picked up by families of lower socioeconomic status. Eventually the names become mainstream, and then finally decline in popularity.
Social diffusion is an explanation of how information spreads, not just names.
My understanding is that unique names and neologism have long been a feature of African-American culture where North American Caucasians followed a family naming tradition. I think what has happened is some celebrities have moved towards a unique name scheme. But it feels like a mainstreaming of AA culture more than anything.
The impetus has been there in Europe. Many nations have/had very restrictive rules about names. They'd only have rules against it if people were trying to do it. I had Swiss friends who were very excited that their daughter was born in Canada so they could name her "Sora" which wasn't in the approved name list in Switzerland.
I would feel bad for Zayden, except that in an alternate timeline where his father was named Brad, Zayden would have been banned named Hunter. So it could be worse. I would rather be Zayden than Hunter.
Aiden is tradition Gaelic and it means "fire".
Caiden is also Gaelic meaning "battle"
Braiden is Gaelic meaning "salmon"
Jayden is Hebrew for "God will judge"
Hayden is old English meaning "hedged valley"
So I’m guessing it’s a combination of dun/den/tun etc being a common suffix in a lot of historical languages, and ‘ei’ being an extremely common diphthong worldwide just… leading to a lot of similar-sounding names that also converge in spelling in modern English?
Unique names and spellings became popular in the US during the 70s as part of the Black Power movement. The politically conscious black parents didn't want to name their children European names, for some reason. The problem is that these black parents had no cultural link to Africa because that had been stolen from them.
Fist came Arab names. I presume this has to do with the NOI and the black celebrities who converted to it. Some of these names are still popular like Omar and Jamal. Of course Black Americans have no more connection to Islam than they do to Christianity, So black parents just started making new names for their children.
American popular culture tends to incubate in the black community and slowly drift into white culture. So it has gone with the unique baby names.
I knew someone with that name. Or at least I assume that was her name because she kept repeating it, like a Pokémon. Incidentally, she was a sex worker.
Those are the names given to the children of all the teenagers I knew who got pregnant in my high school, so they always just remind me of teen pregnancy.
It's been around for a while. Over a decade ago Target ran a cheeky back to school advert featuring a slow pan across school cubbies with lunch pails all labelled with variant spellings of "Braiden". I thought it was hilarious.
I understand the pushback against names like this, and concern for kids receiving these names, but I think it is misdirected. Ya, sure, maybe sometimes the name is literally made up, or in other cases has multiple variations on a theme, but anyone with immigration in their ancestry can tell you that naming conventions do not always move well to other countries. In the USA, we have multiple spellings for names like Muhammed and Dermitt because of this. I don't see why this is a big deal and think it potentially enriches culture.
