One of my passions is doing genealogy. I started researching my family history in college and I've been obsessed ever since. It's truly a gift for your child to pass on your family stories and your family health history.
Show your children your old family photographs. Explain who are in the photographs and when they were taken.
Using copies made from your old photos, letters, and family documents, create a family scrap book.
Make a list of questions, and have your children conduct a genealogical interview about you and your childhood.
Make a family history website together.
Create a family chart on poster board using photos.
Take them on a genealogical field trip to see where their ancestors used to live.
At bedtime, tell them an "Ancestor Story" instead of their normal bed time story. Family stories can be handed down from generation to generation, and helps preserve a family's heritage.
