need some serious help

[tellytubby]

Grrr, i hate choosing a name!! Is that bad?? hahaha
DH and i are hopeless and can't agree on anything.
We dont know the sex of bub, so we need a couple of boys, and a couple of girl names - and decide which suits him/her on the day.

So far for a girls name we both really like Arielle. (Pronounced Ahh-ree-elle)
Another girls name we have is Tayla.. but we don't love it as much - its kinda just there because we're desperate.
What middle name would you think fits well with Arielle?
We're thinking, "A rielle Nyah" (desperately hopeing she looks like an arielle when she comes out, our last name is btw).

Boys names are A LOT more tricky, we can't decide on anything we both like. We've got a list of (2's and 3's - we rate it to eachother to express how much we like them, haha). Our boys list is -
Jacob (will probably be a middle name)
Alby (DH absolutely LOVES this name, after Alby Mangels (sp) but i think its a bit girly.. wdyt?)
Hunter (I love it, DH isn't so keen)
Riley (we both like this name, but don't love it)
Theo (my TOP TOP choice, i absolutely love it, but DH is not keen on it)

Soooo i'm not too sure what i'm asking.
Girls names you think i'd like?
A middle name for Arielle?
Boys names you think i'd like?
What do you think of the boy name Alby??

Thanks... sorry for being long and boring in this post, haha
