Ironically his grandfather was evicted from his homeland:
“Born and raised in Kallstadt, in what was then the Kingdom of Bavaria, Trump immigrated to the United States in 1885. In 1891, he began speculating in real estate in Seattle. During the Klondike Gold Rush, he moved to the Yukon and made his fortune by operating a restaurant and a brothel for miners in Whitehorse.
In 1901, Trump returned to Kallstadt and married Elisabeth Christ. As he had failed to complete mandatory military service and notify the authorities of his departure in 1885, the Bavarian government stripped him of his citizenship in 1905 and ordered him to leave. Consequently, he returned to the United States with his family.”
