Jessica - What a gorgeous name! Can be shortened to Jess, Jessie, etc. and is somewhat common, but not overly used
Tessa - Not a fan, personally. It sounds like a made-up nickname to something, so it just seems like it's missing something to me.
Sienna - Nice name, but just not a fan for some reason.
Pascale - Doesn't seem to fit in with your other name choices, and is a little too "out there" if you ask me.
Alexa - Love this name! It's short & sweet and can be combined with a number of middle names that sound amazing ie; Alexa Lynn, Alexa Genevieve, Alexa Scarlett, Alexa June, etc. etc. I don't think there is a name that sounds bad with it, really.
Taryn - Love this one too!! It's a unique twist to the name Erin and just for some reason really names me drawn to it! It even looks good on paper.
Daniella - I personally like Danielle more with this name, so that it doesn't follow the very popular "ella" trend (Isabella, Gabriella, Bella, etc)
Juliana - This has always been a personal favorite. Gorgeous in every way!
Jocelyn - I like this name only for the reason that it can be shortened to Josie, therefore would probably alter the spelling to Joselyn.
Vivienne - Lovely name that I don't hear much (and I work in the school systems, daycares, etc.)
Devon - I just associate this name with a boy, but I think if you were to alter the spelling (Devyn? Devynn?) it might make me change my liking for it
Leah - So overly used that it isn't even worth using, in my opinion....It's a lovely name, but since it's so popular while being so short, I would alter it into a completely different name that sounds like Leah, for example: Aaliyah, Liliana, Leanne, Aleanna, Loralie, etc.
Suzannah - Beautiful name that is not heard of often and not "out there" at all!!
What a lovely list you have going!!
Good luck and congrats on your little
!!
