My suggestion would be to first try Roots web on the internet. It's a free service and lots of Lilly's have posted info there that you can view. If that turns up nothing, I would go to the Cultural and History Library in Charleston. If you have dates of birth or death they allow you to look up info on microfilm.
If you find anything they will make you a copy for a small fee. I have been there several times and it's very interesting. Newspaper obits are also available.
Sorry I do not have info on your direct line but someone does. If you don't allready attend the Lilly reunion, I encourage you to do so. Someone there could help you. Best of luck in your search.
