Amy:
I'm so glad you posted over here on the Daylily Forum and I hope you find a source for those two DL's named after your grandmother and great-grandmother!!
~ Edited to say: Since it's the weekend, it might be early next week before anyone sees the post so hang in there, I'm sure someone will come along and try to help if they know about those two DL's.
Have a great remainder of your weekend,
Lin
