All I can find from the Qld BDM records 1829-1914 is (and I checked alternate spellings of the names):
Bamberger Charles Leopold Birth Louisa Elizabeth Bamberger 02 02 1885 1885/ 000147
Bamberger Louisa D Bamberger 1890-02-17 1890/ 000006
There is no record of the birth of Florence, nor of any marriage of Louisa. As you see, the father of Charles is not noted on his birth record, nor are Louisa’s parents noted on her death record. There may be more information on the actual certificates, which you can order through
