About Dr. Emil Ohrenstein
the (Czech?) website http://web.ffos.hr/identitetgrada/C1G1I11.html mentions Emil Ohrenstein.
The website http://dasmuseen.net/Wien/Juden/judenliste_143/judenliste_143.htm lists Emil Ohrenstein as living in Vienna at Apostelgasse 39 with his wife Serafine and an Edith Ohrenstein, presumably his daughter, and Karl Ohrenstein, his son. His occupation is listed as dentist.
The website http://bukowina.info/Med.html lists Emil Ohrenstein as a Gemeindearzt living in Illichestie, Bukovina in 1907.
Emil is listed as having been deported to Auschwitz. This is in keeping with the testimony submitted to Yad Vashem by his sister-in-law Friederika, which gives his profesion as physician, though one testimony lists his date of birth as 1873, not 1876 - see http://www.yadvashem.org/wps/portal/!ut/p/_s.7_0_A/7_0_FL/.cmd/acd/.ar/sa.portlet.FromDetailsSubmitAction/.c/6_0_9D/.ce/7_0_V9/.p/5_0_P1/.d/1?related_key=&DTsearchQuery=&todo=2&images=%5B%2F10031908_425_3793%2F107.jpg%5D&imagedescs=%5B%2F10031908_425_3793%2F107.jpg%5D&itemid=926150&q1=PQ61hxOJ2b8%3D&q2=hMRg474BGPwkK5w0y1EyfLpOE8Zb%2Fy%2Fy&q3=XQ1poUZ5hgw%3D&q4=XQ1poUZ5hgw%3D&q5=1l1OP4i0unI%3D&q6=OQsRUPt%2B1jg%3D&q7=%2FNvx%2F8Krk%2F558m7SrvLwZRkKV4lMiijL&npage=&zoomdesc=&victim_details_name=+Ohrenstein+Emil&fromSearch=yes&victim_details_id=926150&imagenum=0&searchfor=1).
