Im not sure about Jaylen for a boy, because if I have a girl I was going to name her Jaelyn. I think it sounds more like a girls name. But thats just my opinion though. Josiah sounds cute and unique.
I like Josiah. It's classic, strong, and the type of name a boy can grow with into becoming a man and it not be awkward.
I don't like Jaylen--to me it sounds too feminine, like Jaelynn or Kaelynn. I also can't picture seeing a man's name on a resume at age 30-50 being called Jaylen, or the CEO of a company or even an auto mechanic, or an old man. The name, to me, doesn't seem like the type of name suitable for a boy, much less a boy over the age of 10.
I love Josiah Lee. It's nice, strong and different...
Im naming my lil boy jayden..i wasnt interested in any other name.
Jaylen's too trendy...there are a lot of Jaylen and Jaden's out there these days. I teach and I'll get 4 or 5 Taylors in a semester, which apparently was the trend for their parents.
Josiah sounds nice, or Joziah if you want to be a little different. :)
