I like them both very much. I wouldn't use them as fns though - it would be a really rare
Juliet who didn't turn out to be
Julie or
Jules, and the only
Eloise I've ever known (delightful kid) was known in her family as Wheezy.
I greatly enjoy
Tessa Juliet. Given enough daughters, I'd have named one of them
Vickie after a good friend, and
Eloise Vickie flows better than
Vickie Eloise, but she'd still have been known as
Vickie.
