Two Chester County families who live in Chester County are among the nation’s elite few who have maintained their wealth across generations. The Dorrance’s of Campbell Soup fame and Comcast’s Roberts family both made the cut for Forbes’ recent 2015 list of America’s Richest Families.

With a net worth of $13.6 billion spread out to an estimated 11 relatives, the Dorrance family is licking its soup-laden lips as the 17th-richest family in the country.

The top 10 are all worth more than $20 billion, and the Dorrance heirs sit just ahead of the beer-enriched Busch family and within reach of climbing up past the Sackler, Hunt and Du Pont families, all of which are worth less than $1 billion more.

Much farther down, among the bottom third of families — all worth less than $2 billion, is the five-member Roberts family, which is tuned in at No. 139 with a $1.8 billion net worth.

“Great fortunes don’t always last,” the article stated. “New technology trumps the old, trends wane, management stumbles. Yet a few of the families who made Forbes’ second annual ranking of America’s Richest Families — we capped the list at 200 members this year — have withstood such challenges.”

The list includes multigenerational families of all sizes but not self-made entrepreneurs already ranked on the Forbes 400 list nor married couples. Rankings are based on assets, including “stakes in public and private companies, real estate, art and cash” minus estimates of debt.
