I wonder what happened to put us off the brrrrr sound. These names aren’t exactly stylish right now:
[name]Wilbur[/name]
[name]Egbert[/name]
[name]Bertha[/name]
[name]Bernice[/name]
[name]Albert[/name] (though I do admit a fondness for this name…how cute is nn [name]Bertie[/name]?)
I actually know someone my own age named [name]Bernice[/name]. 
I dont know why either but I dont care for these names, Bérénice however I really like.
I don’t know, I actually thought the brrrr sound was quite popular ([name]Brian[/name]/[name]Bryan[/name]/[name]Bryant[/name], [name]Briana[/name], [name]Bryony[/name], [name]Braelyn[/name], [name]Bridget[/name], etc.). They do sound a bit different from [name]Wilbur[/name] or [name]Bernice[/name], though, haha.
[name]Wilbur[/name]: Maybe the association with the pig in [name]Charlotte[/name]'s [name]Web[/name]?
[name]Egbert[/name]: Well, this one is pretty explainable. The first syllable is “egg,” and the second sounds like “burp.” When we were kids, my brother used to have a problem with smelly burps, and I called him “[name]Egbert[/name] Eggbreath” any time he would have a flare-up. Plus, it’s a really harsh sounding name.
[name]Bertha[/name]: Perhaps the association with the word “big” and the sound of the word “birth”? It also sounds like a really harsh name.
[name]Bernice[/name]: This is the least troublesome of this list for me, maybe because the “c” softens it up a bit.
[name]Albert[/name]: Also not so bad, but it feels kind of clunky and outdated. I know a [name]Bert[/name], though, and he wears his name well.
The “-ber/-bur” sound is very harsh to me, and most of its pairings feel very old and outdated, so that’s why I don’t like the sounds. Of course, my favorite sounds are J/U/R combinations found in names like [name]Jerusha[/name], [name]Juliana[/name], and [name]Judah[/name].
[name]Albert[/name]'s the only one that I can see coming back any time soon, as I see this name quite often in British birth announcements. The other names still sound too old-fashioned and I can’t really imagine them ever coming back, let alone any time in the near future.
