Raspberry Frills was hybridized by Williamson. The daylilies you have might not have all been hybridized by Simon. But were used in her hybidizing program. That complicates identity even further. We can not even guarantee your pictures are Simon daylilies.
Unless someone else here has some ideas to share I do not know how much help can be given. The lack of pictures is a stumbling block. Add to it the fact everytime I look up one of these daylilies, I am not finding people who own them. My best advice is that your first step is to locate people who actually own them or have pictures of them. Might be a way to meet a lot of very nice people.
May you be blessed with help and success!
Edited to add forgot to say: Perennial Pleasure hybridized by Hardy.
