Diana Lynn Tibert has published a great article in the Kings County (New Brunswick) Record about Christmas cards, She writes, "Yes, Christmas cards are significant to genealogy research." She then goes on to describe her method of tracking "almost every known address for family members regardless if I send them a card. I always buy a large book, so it will last 20 years or more."
