Gap Inc.’s decision to split into two businesses is boosting the fortune of the retailer’s founding family.

Doris Fisher, who started the Gap with her late husband Donald Fisher, and sons William, Robert and John own about 43 percent of the San Francisco-based firm through a series of trusts and limited-liability companies. Their stake in the company is now worth about $4.9 billion.
