I think that's a good possibility Leslie! Great eye!
It's good to see you back Greenleaf1!!
I wish I had time to browse the database and look for you...but I'm leaving town. If you are lucky someone will recognize one of them. The third one should not be too hard to narrow down. But the only way to be sure what they are is to either send a piece of yours to someone who grows that cultivar and let them compare it at bloom time against the known iris, or they may prefer to send you a piece of their named iris and you can grow them side by side and compare all aspects of the bloom.
Bloom time, size, scent, shape, pattern, texture, details such as markings on the hafts and style arms, whether either has PBF (purple based foliage), height....etc.
Good luck! I hope you come visit us again!!
If you don't find any answers check back in a few weeks 2 or 3 maybe. You can send me a treemail and I'll look for you. It's just that I'm going home on family business and don't know how long I will be down there. My mom does not have wifi and the search engine on the phone app is very cumbersome.
