[2] His brother Joseph Zuken also became a Communist politician, and was for many years a prominent alderman from Winnipeg's working-class North End.
With the editorial backing of Dos Yiddishe Vort (a local Jewish newspaper), Ross was elected to the Winnipeg school board in 1936 and served in that capacity until 1939.
