Piroska was Izsak and Esther’s fifth and final daughter. She was born in 1913 in Középlak, just as Moric left for the US, and just before Lajos left to fight in World War I. She came to America with three of her siblings (and Lajos, who returned home to accompany them) in 1926. She married Andre (Andrew) Rosenfeld, also from Kolozsvár, and they had one son, Ronnie. Andrew was extremely successful in business. He and Pearl were at the center of Marmorstein family life for decades.
