Welcome to the iris forum!
Good luck finding your namesake iris! Daphne, great suggestion! Felicia Lynn, Kentucky is part of Region 7 of the American Iris Society, here is a link to their website with contact information if you choose to contact them:

Here's another possible lead: On the wiki iris site, the lone photo you shared is "c. Larry Harder". Mr. Harder was a hybridizer from Nebraska:
http://wiki.irises.org/Main/Bi.... Perhaps he grew and shared that iris? Nebraska is part of Region 21 of the AIS. Here is a link to their webpage:

And if you still can't locate 'Felicia Lynn', we can add it to the "Wanted" thread:
