Hi Boca Joe! Unfortunately I don't think you will be able to find any reliable seed source, since the Deacons are said to not come true from seed. They have to be raised by cuttings, but i have no idea where to find them in US... sorry.
Wishing you a Happy New Year, too! :)

Yesterday I was on Ebay buying some seed and ran across the Deacon geraniums. Had never heard of them so googled and was led to Geranium site. You could find them by typing in Deacon geraniums on Ebay. Wonder if they buying the seed would worth a try or maybe the results wouldn't look like the pictures.
They were very pretty.

thanks everyone!
