I know
Jabez is an age old, Bibical name, but to me it sounds quite trendy. I'd never heard of
Jabez before, and it sounds kinda along the same lines as
Jaden, especially with "jay" as the first syllable.
Jacob's always been quite a common name, and because of it's popularity now, I can see lots of parents turning to
Jabez as an alternative.
I actually don't like this name. The "bez" part is really harsh, and the "jay" part makes it sound trendy. I wouldn't worry about the meaning. Lots of names meaning "sorrow" or "sorrowful", like Brona,
Mary,
Dolores, and people don't hold that against them. "Sorrow" really isn't the worst meaning out there, and it isn't a meaning the child could get teased about, after all.
