Difficult difficult task. Next to impossible. The only chance you have is if by chance it is a mericlone and some one out there recognizes it.
Let's assume that it is a modern hybrid, something within the last 10 to 15 years. It is not like there is a database like "Facial Recognition" for humans. We can't scan the flower and run the image through a software ID program. Even within the last ten years there may have been 500 hybrids of which say 10% got awarded so there is an image to research. But if we find something similar, how can we say for sure? There is no sure way to tell. If it is one of the 450 crosses made but not awarded you virtually have a Zero chance. Forget the name and enjoy it. Call it Tiffany or Sue, it doesn't really matter.
