Two JRI-Poland records relate to a Friederike Riesenfeld who died on 13/04/1866. One gives her age as 39 years, so born 1826-27; she lived in Michalkowitz, her maiden name is not recorded, but her husband is Adolph, a butcher. The other is a record of a burial in Beuthen, which names her husband as Avraham and her father as Aharon Wolff; it gives her Hebrew name as Rivke, a cognate of Friederike and Rebecca.
