Rosalind doesn't have pronunciation issues.
Rosaline does - rose-a-lin, rose-a-lien, rose-a-leen, and that's before you get to the
Rose versus
Roz possibilities.
When I say it, and when all the
Rosalind people I've ever known have said it, it's been Roz-a-lind and they haven't had nns.
Rosanne has a roz as well, but
Rosemary,
Rosamond and
Rosalie all have rose-. Could be different in other dialects.
