How well do you know your family history? How far back can you trace it? Is there practical value in knowing your family’s story?

One of my family members has been delving into our family’s history, and compiling the stories and information she finds. It’s fascinating in itself—but beyond just being interesting, exploring family history is an activity with a curiously biblical ring to it. Family histories and lines of descent were important to people in both the Old and New Testament eras. (If you started reading the New Testament recently, perhaps as part of a New Year’s resolution to read the entire thing this year, you may have been surprised to find that the story of Jesus opens not with the famous Christmas story, but with a lengthy genealogy that traces all of his human ancestors.)

I bring this up because in Bruce Feiler’s recent book The Secrets of Happy Families includes a section on the value of passing on family stories to children. Several of us on the Bible Gateway team have read Feiler’s book, and so we were pleased when he agreed to let us share a short excerpt from it here on the blog.

Want a Happy Family? Tell Your Family History

By Bruce Feiler. Adapted from The Secrets of Happy Families.

I hit the breaking point as a parent a few years ago. It was the week of my extended family’s annual gathering in August. My parents were aging; my wife and I were straining under the chaos of young children; my sister was bracing to prepare her preteens for bullying, sex and cyberstalking.

Sure enough, one night all the tensions boiled over. At dinner, I noticed my nephew texting under the table. I knew I shouldn’t say anything, but I asked him to stop.

Ka-boom! My sister snapped at me to not discipline her child. My dad pointed out that my girls were the ones balancing spoons on their noses. My mom said none of the grandchildren had manners. Within minutes, everyone had fled to separate corners.

That night I began to wonder: What is the secret sauce that holds a family together? What are the ingredients that make some families effective, resilient, happy?

I spent the last few years trying to answer that question, meeting families, scholars and experts ranging from peace negotiators to online game designers to Warren Buffett’s bankers. After a while, a surprising theme emerged. The single most important thing you can do for your family may be the simplest of all: develop a strong family narrative.

I first heard this idea from Marshall Duke, a colorful psychologist at Emory University. In the mid-1990s, Dr. Duke and colleague Robyn Fivush developed a measure called the “Do You Know?” scale that asked children to answer 20 questions. Examples included: Do you know where your grandparents grew up? Do you know where your mom and dad went to high school? Do you know where your parents met? Do you know an illness or something really terrible that happened in your family? Do you know the story of your birth?

Dr. Duke and Dr. Fivush asked those questions of four dozen families then compared the children’s results to a battery of psychological tests. Their overwhelming conclusion: The more children knew about their family’s history, the stronger their sense of control over their lives, the higher their self-esteem and the more successfully they believed their families functioned. The “Do You Know?” scale turned out to be the best single predictor of children’s emotional health and happiness.

“We were blown away,” Dr. Duke said.

Why does knowing where your grandmother went to school help a child overcome something as minor as a skinned knee or as major as a terrorist attack?

“The answers have to do with a child’s sense of being part of a larger family,” Dr. Duke said.

Psychologists have found that every family has a unifying narrative, he explained, and those narratives take one of three shapes.

First, the ascending family narrative: “Son, when we came to this country, we had nothing. Our family worked. We opened a store. Your grandfather went to high school. Your father went to college. And now you. …”

Second is the descending narrative: “Sweetheart, we used to have it all. Then we lost everything.”

“The most healthful narrative,” Dr. Duke continued, “is the third one. It’s called the oscillating family narrative: ‘Dear, let me tell you, we’ve had ups and downs in our family. We built a family business. Your grandfather was a pillar of the community. Your mother was on the board of the hospital. But we also had setbacks. You had an uncle who was once arrested. We had a house burn down. Your father lost a job. But no matter what happened, we always stuck together as a family.’ ”

Dr. Duke said that children who have the most self-confidence have what he and Dr. Fivush call a strong “intergenerational self.” They know they belong to something bigger than themselves.

Religious traditions do a particularly good job at conveying this message. Many Bible stories including overcoming suffering and bouncing back from difficult times. One reason religious communities are so tight is that they understand one of their roles is to help people who are experiencing pain and hardship.

Dr. Duke recommends that parents convey similar messages to their children. Any number of occasions work to convey this feeling: holidays, vacations, big family get-togethers, even a ride to the mall. The hokier the family’s tradition, he said, the more likely it is to be passed down. “These traditions become part of your family,” he said.

The bottom line: if you want a happier family, create, refine and retell the story of your family’s positive moments and your ability to bounce back from the difficult ones. That act alone may increase the odds that your family will thrive for many generations to come.
