OK Chuck. We needed a good reason to get out of the house. Unfortunately it is pushing 100F so we took the air conditioned car and made a picnic trip out of it.
https://www.4peonies.com/The nice lady was very nice, but laughed at our printed picture. The problem is that Peonies are hybridized constantly and hundreds of new varieties hit the market every year. All these new varieties get named by the person who hybridized them. She alluded that you could name it whatever you want and that "Dorcia" might be a unique name for it. The big deal is that all the hybrids are dated, so you will need to find a variety prior to 1949! The closest thing she could suggest was a variety called "Walter Faxon 1904" but she didn't think that was a precise match. Perhaps you have some future derivation of that one:

The nice lady advised that it should be planted VERY shallow and have 6-8 hours of continuous sun. Planted deep or in the shade it will just make foliage and never bloom.

There might not be a specific Peony expert directly within this group. But it doesn't take much extrapolation to get there. Kind of like the Kevin Bacon effect.
