An interesting approach - just to follow up two relatives, sisters of Jane's father, "lost" after WW2. A sad ending for one of them, but frustratingly although the other's adventures were followed through and after the war, just when I wanted it to tell us that her descendants had been found and to produce them for Jane, we came to the end of the programme!
Jane said that her father had gone to Poland after the war to find one of the sisters (without success), but didn't say whether he had also looked for the other sister.
Some one had been working hard in the background, as various relevant documents were found to help the story along as Jane travelled from Poland to France and Switzerland, looking like an extra from "Dr Zhivago" in her fur bonnet.
More of a bit of history rather than genealogy again, but very interesting to follow the various desperate attempts of family members to escape the Nazis as they took over parts of Europe.
