Daniel Gluck in the Bronx

My cousin remembers that my great-aunt Mary Schwartz boarded with her 2d cousin Daniel Gluck and family in a Bronx apartment after arriving in NYC from Ungvar, about 1911-1912. Daniel had two daughters: Beatrice (a buyer for a lingerie firm?) and Ruth. The family started a furniture store in or near Paramus NJ in one of America's first shopping centers, perhaps during the mid-1930s. So far no luck tracing them but it's some kind of lead.
