Cathi, I was thinking -- if you don't get these stories from your Mom and other relatives, one day it will be too late as the older generation will have forgotten the details or passed on. You can tell her you're researching this for your own memories, and won't publish a book in her lifetime. This seems like a fair compromise but of course you need to do what feels right for you.

You're honoring your grandmother and her spirit by writing these memories, not shaming her. Maybe you can make your Mom understand how much this is honoring her and not an expose.
