Who would you invite to a fictional celebrity dinner party?
I'd like to have a mix of guests from all walks of life, scientists, movie stars, great world leaders and others.
But what if you could spend time talking to your ancestors - or your descendants? What would you want to share with them? What would you want to learn from them?
In our family history research, we try to learn as much as possible about our ancestors, including how they lived, what they did, what their interests were and other information that helps us understand who they were as real people.
Even with all this data you've collected, what would you like to ask your ancestors, if you had that opportunity?
The video below is a play on this concept. Actor-filmmaker Jeremiah McDonald has a conversation with himself, based on a tape he made some 20 years ago.
So, if you had such a moment, what would you tell - or ask - your ancestors or descendants? Let us know in the comments below or on our Facebook page.
