Vote for Sierra, it's perfect.
I really like Adrianna and agree with Saracita in her impressions of the name! I like it with beau and the last name and I like the difference in syllable count to soften the last name. They only one I don't care for is lacey. It is too rhymey with the last name and too much like lace and bows gussied up (as mentioned). Plus I don't think it carries as well theocracy a lifetime as Adrianna does. The more I think of Adrianna the more I'm in love with it for your name and family set.
-Harper Gussy - Sounds great, but Harper is popular and rising, so if that's a problem maybe it's not for you. Makes me think of- Haven, Piper, Phillipa, Pippa, Poppy, Penelope, Olive, Hadley, Jasper, Mica, Lark, Larkspur, Laken, Winnie, Darby, Darcy, Delaney, Cassidy
-Lacey Gussy - too rhymey? Yes it is rhymey to me. I love Lacey!
-Lyla or Lila - which way would you spell? I am leaning towards Lyla to make it easier (I'm more for easy pronunciation than unique) I like the look of Lila much more. Makes me think of- Lilac, Violet, Viola, Mila, Isla, Lillian, Lilla, Calla, Liliana, Linnea, Leila, Linda, Libby, Willa, Willow, Kyla
-Adrianna Gussy -- love this, but it seems like an Italian first name with a rather cowboy last name. Does it flow? I think it works. I like a longer, flowy-er name with your surname!
-Teagan Gussy- It works. Makes me think of- Regan, Teal, Megan
-Sierra - this would go with my nieces also city names, Viennah and Savannah. This works. The connection is nice, but would you feel tied in to the theme, like you would need to come up with another place name if you have another child?
-Leighton / Layton- I like Leighton much more and I think "Lay" could be easy for teasing. I think the longer style name is nice with your surname, but this has more of a modern style like the rest of your list.
Thanks!! Bed rest is challenging but I know its worth it! Every day she stays put should decrease the NICU time by about 4-5 days so each day is an accomplishment!
My thoughts on the names:
Harper Gussy - I like Harper, she's spunky has great literacy associations and sounds really sweet. Harper Gussy sounds awesome.
Lacey Gussy - It's far too rhymey!
Lyla/Lila Gussy - My favourite is Lila the spelling is far prettier. Lila is so sparky.
Adrianna Gussy - Adrianna is actually lovely, she has a great Italian feel, but I prefer the Adriana spelling.
Teagan Gussy - I find this name unattractive. I do see the appeal but I just find her harsh. She isn't my thing.
Sierra - Not my cup tea I understand the connection with your nieces but I think their are other prettier city names like Geneva for example.
Leighton/Layton - Leighton is the better spelling. Looks classier.
My favourites are Lila & Adriana.
sorry to hear you're hospital bound :( hope you have a healthy, somewhat uneventful delivery!
even though it's a hot item, i think i like Harper the best.
