Merida is too Disney and I don't care for Sawyer on a girl. I think Ava is beautiful.
I like Ava Layne and Merida, but not with Marie. Echoing previous comments that Merida Layne would be nice.
I agree that Merida Layne and Ava Marie are more balanced combos in sound and feel. I would spell Layne without the y. It's unnecessary and looks "yooneek".
I voted for Ava Layne because Merida Marie is too matchy matchy as a first and a middle name for me. Sawyer is a boy's name to me so a no go.
1. Merida Marie
2. Ava Layne
3. Sawyer Belle
If the middle names are interchangable...
1. Merida Belle
2. Ava Marie
3. Sawyer Layne
I chose the name!
It's a secret. Don't worry -- I'll post a birth announcement when my little princess comes into the world!;)
