As an avid genealogist I have learned that if another person is not interested in their ancestors, you may as well stop talking about them. Not so with children. They will listen for as long as you can talk. They will ask you 'why?' They will laugh at your stories. They never seem bored or wonder when you are going to stop talking. Lastly, they love stories. They seem to think the things you are telling them about when you were a little girl are just so great! I tell them what they call 'ancestor stories'. Then, the next time I see them they will say, "Tell me more ancestor stories, Grandma." Then, of course, I get started!
