What do you think of...

Ghislaine (is it spelled any other way? This spelling looks strange to me)
Corinne

as girls names? Not necessarily together as sisters.

I hope I don't sound catty, but OP was asking about Ghislaine, not Ghislain.

I personally consider Ghislain and Guilain two different names, but I suppose Wiki indicates different.

Are you French or francophone?

I know, but Wikipedia redirects the search for "Ghislaine" to the page "Ghislain" and I didn't alter the quote because the pronounciation of the first syllabe is the same anyway.
I must say I had always read "Jis" too until I heard a Ghislaine pronouncing her name as if it was "Guilaine".
According to what I read (not only on Wikipedia, where I just went to look for a quote to prove I didn't talk whithout knowing), Ghislain and Guilain or Ghislaine and Guilaine have the same origine, Guilain and Guilaine being just alternate spellings for the newest prononciation.

I'm Belgian and I live partly in France.
