I conducted a search for the name "Mania Orensztajn" requesting an exact match, however; there were no nmaes that turned up. A fuzzy search Gave the name "Mania Urensztajn," could the student's "U" have been mistaken for an O? She is the right age having been born in 1933. My fiding and request for approval is submitted on the basis of this question.
(the name Urensztajn is not listed in the Student list)
After considering the comments provided by the ushmm and additional research I have come to the agreement that the child is mostlikely Mina because of her birthday
As requested I have listed the data base used on Jewishgen.org. You have to create a user account (free) in order to use the resources, and there is a lot of sifting through the information, but once you locate the student and the address, simply match the address to other poersons listed in the data base. It's an excellent tool quick and easy to use to give these children their lives back in some way.
