My great grandfather had four sisters, maiden name Belostotsky (Belostotskaya), who had lived in Berlin some time between 1900 and 1920, and subsequently emigrated. Three went to the US, one went to Australia. Unfortunately, they were all married at the time of immigration, and I do not know their married names. I was thinking I could try to find the sister who went to Australia by her maiden name, but have had no success on a brief search using FindMyPast, searching ships' manifests, NSW deaths, ACT deaths, QLD deaths, and WA deaths. While I have no confidence whatsoever that I would have found any records given the nature of the search interfaces and the indexing functions, I am also wondering about a better way to select where to search and how to do it. Suggestions welcome!
Here's a picture to gauge their ages. Judging from the dress style, this may have been taken around the turn of the century. The back gives their names (in Russian); their youngest brother (my ggfather) was born in 1883.
