Lisa,
I agree that that second iris is a looker. I have a thing for smoky purply irises especially and have just added Quaker Lady and President Pilkington this year so that I can try to ID one of the plants I've had for a long time. Some of the pictures of Quaker Lady do look a lot like yours. Amitola is another possibility that came to mind. Also, if you haven't already discovered it, I'd recommend visiting the Historic Iris Preservation Society Page (
http://www.hips-roots.com/). They have lots of resources for identifying historic irises. BTW, much of the online material is accessible to anyone, but membership is also definitely worth the low cost ($10/year)--it gets you a couple issues of their magazine, the chance to buy irises at the annual sale, and access to the online forums ("Communication Center"), frequented by people with particular knowledge about historics.
