Finding my Grandfathers records - Berlin help
I am trying to find out a little more about my grandfathers immediate family.
As I know things my grandfather Bruno Bombera was born on 9th September 1923, in Berlin.
He was one of 5 children, we think he was the youngest. His memory was not great regarding his siblings and thus I would love to just try and find/confirm their birth records.
He mentioned he had a brother who was killed aged 14 by a tram, however I have found a death register which says Johann Bombera was aged 4 killed by a tram.
I know of his brother Franz and sister Cecilia, although very unsure of their Dates of birth.
the final piece of the jigsaw is another sister, my grandfather mentioned that he remembers his mother going to the hospital/institution to see her and that she had a funny face (we could speculate perhaps down syndrome?) he could never remember her name, however he does remember that he was taken by the Nazis and it was later told that she had died of pneumonia (which I think was common reason for those tested on during WW2).
His father Vicentius Bombera, we found listed as a mechanic I believe and in Lichtenberg.. his mother listed as Sophia Pischke in the few documents I think is actually Zophia Piszczek.
my grandfather mentioned that his grandmother ran a pub.
my priority is to try and find the birth records for the Bombera children including my grandfather.. I would imagine he would have been born in the lichtenberg area, especially as that is where Johann was also killed.
would anyone be able to potentially push me in the direction of where I might find such records if they exist, Germany during the war.. from all the records of Vicente and Zophias records and their family I can presume that the Bombera family were of Catholic faith.
so my initial thoughts would be to search Catholic records of the lichtenberg area but I seem to just hit a stumbling block as to do these even exist?
Any advice on how to go about this research would be incredible.
