A man digging into his family past to find out about his mysterious grandfather has been documenting his discoveries into a podcast.

Andrew Evans from New Barnet is a video editor and as a side project has been creating the Unbordered Podcast.

The 37-year-old started his show in December after agonising over his European identity with hopes that if he could prove his grandfather’s European heritage so he could claim citizenship.

He said: “As I awoke to the news that the UK had voted to leave the European Union, I felt as I guess many librapolitan millennials did that a part of my identity was taken away.

“Determined to avert this Brexistential crisis, I set out to find out more about my enigmatic grandfather.

“There may also have been a more selfish motivation of somehow using this ancestry to hold on to my EU passport.”

However, after some research, he found out that his grandfather, Adolph Lempert, a Jew born in Lvov in south west Poland now modern day Lviv in Ukraine – a non-EU country.

He and his family lived in the Ukrainian city in which a third of the population was also Jewish.

Mr Lempert who had changed his name from Zuckerkandle at the onset of the Second World War after his family had moved to Belgium.

In May 1940, when the Germans had arrived in the small country as part of its lightning attacks across western Europe, Adolph fled Belgium, by taking a perilous route through France which was at this time also under assault by the German Army in the hopes he could make his way to Portugal.

Mr Lempert’s family were all seized and taken to Auschwitz, Adolph would be the only one to make it alive to the United Kingdom.

Surviving on his wits, Mr Lempert would say he was Dutch or Belgian depending on whom he was speaking to and never tell anyone he was Jewish.

Eventually, Mr Lempert would get to the UK and volunteer with a Dutch contingent in the RAF as a reconnaissance navigator.

Mr Evans would say: “I believe he was a charming devil, able to talk his way out of many situations and survive.

“He most certainly was not a coward by any means he got back into the war.”

After the war Mr Lempert would integrate himself into his new home and live in Cockfosters, becoming in every way typically English, he would get married and find work later in trading rare French stamps in Piccadilly.

However, when Mr Lempert’s daughter was about 15 he left his wife for a younger woman and moved to France he would never see his family again.

“I never met my mother's father, and that may be part of the appeal.

“I knew he'd somehow survived the Holocaust, made it to London, changed his name, served in the RAF and settled in England.

“But the details were few because of something he did in his 'controversial third act' that meant he never saw his daughter.”
