Note: Keller, Ernst Berthold, Sohn von Keller, Jakob, wurde am 2. März 1913 in Bali geboren und starb dort am 8. März 1913. - Jakob Keller hatte kein Kind namens Lukas. (RI). - Keller, Berthold Erwin, Sohn von Keller, Erwin Emil wurde am 18.02.1939 in Besongabang geboren und am 07.05.1939 in Fotabe getauft. Vermutlich handelt es sich hier eher um Keller, Berthold Erwin, da Keller, Ernst Berthold als Tauftag nur den Todestag in Klammer angegeben hat. Jedoch hatte auch Keller Erwin Emil kein Kind namens Lukas. (MS 01.1999).; Note translation: Ernst Berthold Keller, the son of Jakob Keller, was born on 2nd March 1913 in Bali, and died there 6 days later. - Jakob Keller had no son called Lukas. (RI). - Berthold Erwin Keller, the son of Erwin Emil Keller was born on 18th February in Besongabang and baptised 7th May 1939 in Fotabe. So this photograph probably refers to this Berthold Keller. The Berthold Keller who was born in Bali only has the date of his death entered in the column for the date of his baptism. There is still a problem, however: according to our registers Erwin Emil Keller also had no child called Lukas. (MS 01.1999).
