I don't see how this name can sound attractive at all, to be honest.
It sounds like a word, or like a disease, I don't know...
In
German, it's just a cutesy nickname for
Greta (or
Margareta etc., anyway), and it sounds pretty cute for a little child, but in English it sounds uuaah to me ;), not like an attractive name at all.
I do love
Bonnie and
Leigh, however, but don't like
Suzette.
Susanna is cool as a mn, though.
I'd like
Gretchen Bonnie and
Gretchen Susanna(h).
Gretchen Leigh doesn't flow, somehow, and the names don't really make a nice combo together, imo.
Leigh makes it sounds so meaningless, somehow...
Gretchen Bonnie sounds too cute and not mature, however, but the combo itself is pretty nice.
Gretchen Susanna(h) would be like perfect, to me.
Or what about...
