Oh, that sounds like a fascinating film, and if the groom were to be Jewish, that would add another layer of an older truth coming back to the village.

Incidentally, and elaborating on that, Poles are now the UK's second largest ethnic minority, so his potential origin makes sense. Though if he grew up in the UK he's more probably the grandchild of those who stayed post-war, rather than those who've arrived post Poland's accession to the EU. Which of course just deepens the story further if he's Jewish.
