@Char - I have to thank you again for pointing me in the direction of Ken Cobb. I have been so busy these last few weeks, but he has taken the charge and run with it, putting as much effort into finding Mildred Primos' cultivars as I have.
Unfortunately, he is running into the same lack of responses from contacts that I was. I'm not sure why no one is even responding to us, even if just to say 'sorry, I don't have the info you want.' It's very frustrating for me and I'm sure it's frustrating for him, too. :-/
