A New York local news site says Paul Rosenberg’s granddaughter is opening an art gallery on the Upper East Side:

Marianne Rosenberg, a New York City-based lawyer, recently signed the lease on a 1,500-square-foot ground floor of a townhouse located at 19 E. 66th St., said Jill Lovatt, the leasing agent who represented the space. The townhouse, which is located between Fifth and Madison avenues, was formerly home to David Tunick, Inc., a gallery that specializes in fine drawings from the 15th to mid-20th centuries.
