Those are all cute names! I'll be considering themI really like Lucy. I must really like names the end with the sound "e". I have 27 chickens with names and 13 of them end in either ie, i, or y.
I was thinking maybe Lizzie for one, but I already have so many names that end with that sound. I guess it couldn't hurt to name them Lucy and Lizzie! lol
It's hard to find girl names (apparently) that don't end similarly. In my daughter's kindergarten class there are 12 girls (I think) and ALL of them - Every single one - ends in "a". At least in your case they end in a similar sound and not all with the same last letter.
Personally I really like Lizzie and Lucy, I think they sound really cute together!!
