I've been looking for some further proof of Shemp's birthday as well. His granddaughters' site states the 17th, so I was going with that. I know the death certificate states the 4th, but if that's the only document that does, and several others point to St. Patty's Day, I would likely think that would have been where an error was made. People are so disorganized, especially when it's a sudden death, as Shemp's was. If anyone comes up with anything more concrete, I'd love to hear about it.
