(CNN)Donald Trump’s grandfather was kicked out of his native Germany for failing to do his mandatory military service there, a historian has claimed.
A local council letter from 1905 informed Friedrich Trump — who had become a United States citizen — that he would not be granted his German citizenship back and that he had eight weeks to leave the country or be deported, German historian Roland Paul told CNN Tuesday.
He also claimed that Trump had illegally left Germany, failing to notify authorities of his plan to immigrate.
The Trump camp did not immediately respond to CNN’s questions on the research.
According to historian Roland Paul:
Friedrich Trump was born in 1869 in the German city of Kallstadt and joined his sister. Katharina, in the US in 1885. He was first hired by a hairdresser. In 1892 he became a US citizen and changed his name to Frederick.
He then moved to the small city of Bennett and opened up the New Arctic Restaurant and Hotel that the Yukon Sun newspaper also considered a brothel. Trump returned to Kallstadt in 1901, and in 1902 married 20-year-old Elisabeth Christ.
The couple moved to New York and in 1904, their daughter was born. He and his family returned to his hometown that year and Trump applied to get his German citizenship back as his wife wanted to leave the US.
The Kallstadt council rejected his request because he had failed to do his military service and notify them of his emigration.
The findings have sparked interest as President-elect Trump vowed to crack down on illegal immigration in his election campaign.
“Trump talks against illegal immigration, so I think he should remember his own family story from time to time,” Paul said.
Trump proposed a wall be built between the US and Mexico as the centerpiece of his anti-immigration drive. He has also threatened to deport undocumented migrants who have committed crimes in the US.
‘Trump wouldn’t exist’
Paul came across the document on Friedrich Trump’s threatened deportation in state archives and also found several letters from him pleading with authorities to allow him to stay. Paul mused on how this one administrative decision seemed to have changed the course of history.
“I have to say this kind of letter wasn’t unusual back then,” Paul told CNN.
“But if they had accepted him back at that time in 1905, Donald Trump wouldn’t be in the US — in fact, he wouldn’t exist.”
He said the eight week deadline was extended as Friedrich Trump said that his daughter was ill. But he was finally forced to leave two months later.
Trump’s father was born in the US, where he met Trump’s mother, Mary Anne MacLeod, who hailed from Scotland.
Paul, now retired, carried out his research earlier this year when he was Director of the Institute for Palatine History and Folklore in Kaiserslautern, but his research caught public attention on Monday when the tabloid Bild published his findings.
