Script Font for Name with Suffix

Hello all,
I am designing an invitation and I need to find a traditional script font that will work with a name with a suffix - like John Smith III. The III at the end looks terrible with a script I. (I had wanted to use Edwardian Script.)

I know swashes and alternates can solve the problem, but I've had to look at each font in InDesign to see if alternates are available and I can't find a way to look for that on the major font sites. I'm on a PC with CS3.

Any suggestions?

Thanks
