As I grew up half German in England in the 1970s, my German heritage was confined to the few curios my grandmother had brought here after the war: a signet ring, a cigarette case, a scrapbook with some missing pages…. She’d changed her name, she’d changed my father’s name, the nation she came from lay in ruins — but from this salvaged bric-à-brac I pieced together the story of my father’s German family, a story they’d done their best to bury in the country they’d left behind.
