Hi from Paris,
My GF Avrom Zysman left Lodz just after WW1 in 1919 (and just before being drafted in Polish army) and lived 4 years in Germany before immigrating to Paris in 1924.
I have some facts concerning his and perhaps your Russek's history.
Then 1933 with Hitler's nominated as chancellor, or 1938 Kristal Nacht.
These three dates had been red warnings when Jews could decide to leave Germany before it was too late.
My GF Avrom left Germany in 1924 : I am well and alive and living in Paris to tell his story.

I am curious if it is known if many Jews from Lodz moved to Germany, specifically Falkenstein, in the years after World War 1, and if so why. I know of one relative of mine, named Ezra Russek, who moved there with his family. There is another Russek who made the same move with her husband at around the same time, and I'm trying to establish if they were related, or if it was a common move and this is just a coincidence (it was a common name also, I recognize, but there are other facts that suggest a connection).
Any information would be appreciated.
