My maternal grandfather Laurence Michael Barnett spent the 1950s as a committed Communist Party member, who also happened to be secretly filing reports to ASIO about his comrades.
I’ve recently discovered that wasn’t his only secret.
The first clue to a different secret history came when my Uncle Stephen spat into a plastic tube. The DNA results made no sense: 29% Jewish ancestry in a family tree we traced back to Anglo-Saxons. My uncle stared at his laptop screen for a long time, then emailed me.
"Either this thing is broken," he wrote, "or we've got the wrong family."
We had the wrong family. Or rather, we'd been missing half of it. The missing link was the real identity of my grandfather’s mother Jessie Sheba Barnett. Uncovering who she was would unlock the mystery behind Laurence’s compartmentalised life – and reveal the secret he'd buried deepest of all.
We had always wondered about Jessie Sheba Barnett, particularly her unusual middle name wedged between two common ones. We had photos of a dark-haired, dark-eyed young woman, but nothing else.
After Stephen’s DNA discovery, we began tracing through records and databases, trading census and shipping registers from the early 20th century. What we found challenged everything we thought we knew about our family – uncovering our unknown Jewish connection and a century-old scandal.
This Jewish woman, a Polish émigré via East London, worked as a 'hostess' alongside her Australian lover and his legitimate family
