They seem to be accurate from what I can see.Kayla
can't mean "crown of laurels" in Hebrew as Atarah
means "crown" and they're clealy not anything alike.
means "beloved" in Arabic, not Kaylin
The thing about names like Kayla
is that they're trendy, and many, many name sites make themselves appealing to big audiences by giving trendy names with fairly boring meanings, like Kayley
and its variants, nice, interesting or appealing meanings. BtN doesn't do that, as I'm sure you've seen, so yes, all of those names can be traced back to the Irish Gaelic Kayley
As for Katherine
- I haven't had a chance to delve into the etymology myself, but I trust the judgement of Mike
C (site creator) when it comes to controversial meanings. Chances are, he's right.
