I read the responses and i also thought it was a trendy spelling of
Ireland. I wouldn't personally use
Ireland, but I think the name is okay, so I like Irelyn. But then I saw that it isn't pn like that...but I really like Aralyn! One of my favorites is
Arabella and it reminded me of that. Also, on Real World Las Vegas (two or three seasons ago now) there was a girl named Irulan (air-uh-lon) and it reminded me of that also. i think I like the Aralyn spelling better to avoid confusion with
Ireland.
As for your mns, my favorites with the name are
Renae or
Rae (although where I am from both of those are really common mns)!!
