Chaja Estera Kac was chosen to identify Ester "Chatul" Kac due to the birthdate being most likely that of a student at School #9a. Two entries were found with the names Chaja Estera Kac and Estera Chaja Kac. Estera Chaja Kac may be an alternate spelling/arrangement of first and middle names. the Chaja Estera Kac entry listed the birthdate as 1932, the Estera Chaja Kac entry listed 5 July 1932. These entries were determined to be for the same person since the SCHULZ 52 1A address was the same for both. The second ghetto address was listed for the Chaja Estera Kac entry that only listed 1932 as the birthdate. SCHLEGEL was not listed as a street name or abbreviation of a street name. A Google search of SCHLEGEL did not yield anything pertaining to Lodz ghetto street names.
