@Legalily - I checked the AHS database for two of those (I'm lazy), and they aren't listed there either.
My best guess is that these plants were never registered, and are being sold under the "garden names" of the originator. You can contact the nursery where you got them from, and inquire.
That is too bad, because somewhere down the line someone may register a daylily under those names, and then there is potential for confusion.
Case in point: 'Little Miss Sunshine' is a tet that was registered with the AHS in 2010. However, there is a plant that is a "selection" of 'Stella de Oro' which is being sold in some nurseries under the same name. (I mentioned this in a note under the ATP entry, and also sent an email to the one nursery that I know for sure is selling this, which prompted a reply from that nursery, which you can read in the response to my note.)
If the nursery is indeed (as it seems) selling daylilies under garden names, you might encourage them to register the plants under the AHS, so as to avoid more plant confusion.
