 Katharina Trump's son, Frederick Trump, had immigrated to America in 1885 at the age of 16 and made his fortune with restaurants in the Klondike Gold Rush.When he returned to Germany in 1901, he wooed Elisabeth over the objections of his mother, who felt that her prosperous son could and should find a bride from a wealthier and more refined family than Elisabeth's.Nonetheless, Friedrich proposed to Elisabeth, who accepted, and they were married on 26 August 1902.
