I too am a relative . My mother was Rose Broslovsky daughter of Abraham and Sophia .
Sophia was a Step daughter according to family stories.
The is some good (and funny) documentation about Samual ( Sam ) Trager and his WW1 escapades .. I have copies on my computer of original letter written by his mother to the Arrmy requesting a discharge ..
I recall some stories about Uncle Misha comming to Australia and asking my folks to go and live in Indonesia where he had a plantation ( Iwa stoo young at the time or not born so this is only family say so . Unfortunately my mum is not aware enough to tell more theses days she is 94 . Her younger sister Sadie is still going strong I will pass this info over to her and see what she recalls .
