I've received two responses so far. One sibling says that he will jot down some things in the next few days and that Dad sometimes wore a hat - not often, but when he did it was one like Al Capone's. So far, so good :) That would be one of the pros. I had to Google images of Al Capone to see what that might look like. Here's one photo:

The second sibling emailed that she didn't have any good memories of Christmas and then related a story about a gift gone bad from when she was 15 or 16. So, I guess I won't be including that story :) That would be one of the cons.
Hopefully, I'll hear from the other three and be able to put something together. In the meantime, I'll start writing my own memories so they are ready to insert when the time comes. Maybe I'll read them to my own grandchildren around Christmas time. I bet they'll like that!
