While interviewing my maternal grandmother about her parents and grandparents, she tried to list her mother's mother's siblings (there were eleven of them). She could not remember all their names, so she stopped the interview to call her older sister to see if she remembered them.
This turned out to be the best interview interruption ever, as my great-aunt turned out to have a family bible with my great-great-great grandparents, their birth dates and their eleven children's names and birth dates listed. I did a happy dance that day and will be sure to do another when I visit her in a couple months and get to make copies of it!
