The Trump family has been making headlines for decades – first, as bigwigs in the real estate world, and now as some of the most powerful politicians in America. Recently, a new member of the Trump family stepped into the spotlight. President Trump’s niece, Mary Trump, is set to publish a book titled Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man on July 28, the Daily Beast reported. In the book, Mary is said to reveal that she was a source behind The New York Times’ investigation into her uncle’s finances and says that he mocked his father, Fred Trump, as he suffered from Alzheimer’s disease in his later years. Coincidentally, another book, The Art of Her Deal about Melania Trump, also made headlines last week. Written by Pulitzer Prize-winning The Washington Post correspondent Mary Jordan, the book says that Melania renegotiated her prenup after Trump’s presidential win in 2016 and that there was friction between Ivanka and Melania in the early days of Trump’s tenure, something the White House has called “totally false.” Melania Trump: what does the US first lady even do all day? Here’s a look into the dynasty behind the first family of the US. Donald Trump’s grandfather, Friedrich Trump – born Friedrich Drumpf – emigrated to the US from Germany in 1885 at the age of 16 Friedrich Trump was born in Kallstadt, Germany, and arrived in New York on a steamship. “He didn't know English. He couldn’t possibly have known English. He didn't have anything like a high school diploma. He was literate, but in German,” Gwenda Blair, the author behind the 2000 book The Trumps: Three Generations That Built an Empire told The Washington Post . Friedrich Trump’s family in Germany had modest means and ran a small vineyard. Once he landed in New York, he lived with his older sister on the lower east side in Manhattan. A few years later, Friedrich moved to the Pacific northwest, where he ran multiple businesses, such as restaurants and hotels, across the region in former mining towns during the gold rush. For years, the family claimed they were Swedish According to a 2016 New York Times story, the Trump family for years claimed they were Swedish, apparently born of a desire to make good with their Jewish friends and customers. “He had a lot of Jewish tenants and it wasn’t a good thing to be German in those days,'' John Walter, Donald Trump’s cousin, said of Fred Trump, Donald’s father, alluding to the time between World War II and the 1980s. The Trump family’s roots can be traced back to Kallstadt, a small German hamlet. The town also produced Johann Heinrich Heinz whose son, Henry J. Heinz, is the man behind Heinz ketchup. 5 things about Tiffany Trump, the low profile daughter of Donald Trump In 1902, Friedrich married Elisabeth Christ, a former neighbour in Kallstadt Elisabeth, who was 11 years her husband’s junior, was five when Friedrich first left Germany. He met her during a visit home in 1901. Elisabeth moved to America with her husband after their wedding. By then, Friedrich was an American citizen. He closed his businesses on the west coast and turned his attention to Queens. In 1904, the family went back to Germany only to be deported soon thereafter. Government officials ruled that Friedrich be deported as he had never fulfilled his mandatory military service and had failed to notify authorities of his move to the US. Friedrich wrote a letter to prince regent of Bavaria in 1905 requesting that he be allowed to continue to live there, but his petitions were rejected. Upon their return to the US in July of 1905, Friedrich, Elisabeth and their daughter lived in the south Bronx neighbourhood of New York City. Friedrich Trump died of the Spanish Flu in 1918 Friedrich Trump was 49 years old when he fell sick in May 1918. He started feeling ill in the afternoon and died “almost immediately” according to The Washington Post and biographer Gwenda Blair. Estimates from the Centres for Disease Control and Prevention (CDC), suggest about 675,000 people died of the Spanish Flu pandemic in the US. Friedrich and Elisabeth had three children: Elizabeth, Fred, and John Elizabeth, Friedrich’s oldest and only daughter, served as a bookkeeper for her younger brother Fred during his early years in the real estate business. Her son, John Walter, was a self-appointed Trump family historian. Friedrich’s youngest son, John, has received significant media coverage over the past few years, in part because of President Trump’s repeated mention of his uncle throughout his presidency. At one point, he called his uncle “a great super genius”. Most recently, John’s name came up while discussing the coronavirus. John Trump had a storied career as an engineer, working at the Massachusetts Institute of Technology for more than 40 years. Among some of his most noted contributions was a breakthrough in X-ray technology that advanced cancer treatment and research. Frederick Christ Trump, Donald Trump’s father, was born in 1905 soon after his parents were forced to move back to the US from Germany According to a 2018 Independent story, Fred Trump’s first business venture was adding garage extensions to houses as a teenager. Fred Trump built his career as a real estate mogul in the mid-1900s through construction projects in Brooklyn and Queens and parts of Pennsylvania and Virginia during World War II. His July 1999, a New York Times obituary called him a “self-made man” who built “27,000 flats and row houses in the neighbourhoods of Coney Island, Bensonhurst, Sheepshead Bay, Flatbush, and Brighton Beach in Brooklyn and Flushing and Jamaica Estates in Queens”. In 1973, the Justice Department sued the Trump Management Corporation for “discrimination against [B]lacks in apartment rentals”. Fred and Donald were both named as defendants on the suit. Donald Trump called the charges “absolutely ridiculous”. At the time of his death, his estate was estimated to be somewhere between US$250 million and US$300 million. Melania vs Ivanka Trump in fashion – who dresses better? A 2018 New York Times investigation found that President Trump has received more than US$400 million from his father’s real estate empire, adding that “much of this money came to Mr Trump because he helped his parents dodge taxes”. Responding to the investigation, the Trump family said, “All appropriate gift and estate tax returns were filed, and the required taxes were paid. Our father’s estate was closed in 2001 by both the Internal Revenue Service and the New York State tax authorities, and our mother’s estate was closed in 2004. Our family has no other comment on these matters that happened some 20 years ago and would appreciate your respecting the privacy of our deceased parents, may God rest their souls.” In 1936, Fred Trump married Mary Anne MacLeod, a Scottish immigrant The couple met and fell in love at a dance. MacLeod had immigrated to the US from the Scottish Hebrides in 1929 as a teenager. Like Friedrich Trump, she already had family in the US. She became a naturalised US citizen in 1942. Fred and Mary Trump had five children: Maryanne, Fred, Elizabeth, Donald and Robert. Trump’s oldest sister, Maryanne Trump Barry, 83, is a retired federal judge Barry has degrees from Mount Holyoke College and Columbia University. She has a son, David Desmond, who is a clinical psychologist. According to Town & Country magazine, she was nominated to the US District Court by President Ronald Reagan 1983 and the US Court of Appeals by President Bill Clinton in 1999. “I knew better even as a child than to even attempt to compete with Donald. I wouldn’r have been able to win. He was building models when he was very young. Huge buildings,” Barry told New York Magazine in 2002. A Washington Post article referred to Fred Jr as “tall, blond and movie-star handsome” and “the opposite of Donald Trump – soft-spoken, playful and often joking”. Fred died in 1981 at the age of 46. He struggled with alcoholism and President Trump has said that Fred's death has had a “tremendous impact” on him. Fred had two children with his wife Linda Lee Clapp – Fred Trump III and Mary Trump, both named after his parents. On June 14, the Daily Beast reported that Mary Trump was set to publish a tell-all book about the president. The book, titled Too Much and Never Enough , reveals that she was a source in the Times investigation into the family’s finances.
