Lydia makes me think of
Winona Ryder's character in "Beetlejuice". I had an aunt named Lydiet (lid-ee-et).
I love
Delphine.
Lydia doesn't do it for me. Even though it's pretty, unusual and a real name I am not crazy about it. The combination of
Lydia and
Delphine is a good one but I think you can do better.
