But back in the 20’s and 30’s in Europe when Anna Anderson was pursuing her claim certain of her opponents claimed to have found out that she was actually a Pole named Franziska Schanzkowska. Ms. Schanzkowska has relatives still living in Poland and DNA tests on the hospital tissue sample proved that Anna Anderson was related to them and probably was actually Franziska Schanzkowska.
I recall someone kin to the Romanovs hired a private detective to check her out not long after her story began to get some press.
He basically reported back the facts and they were exactly what they turned out to be.
