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.

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.

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. President Trump is looking into whether he can take legal action to stop Mary from publishing the book, the Daily Beast also reported.

Elizabeth Trump Grau, 78, has stayed out of the family business

In The Art of The Deal, President Trump called Elizabeth “bright but less ambitious”. Elizabeth attended Southern Virginia University and went on to work at Chase Manhattan Bank, although there are conflicting reports of her exact role at the financial institution. She’s married to producer James Grau. The couple lives in Florida.

Robert Trump, 72, the youngest Trump sibling, is a former top executive at The Trump Organization

Robert Trump told Page Six in 2016 that he supported his brother running for president “one thousand per cent”. He also donated US$100,000 to the Trump Victory PAC. He’s now retired and living in Hudson Valley, New York.

Donald Trump married his first wife Ivana Marie Zelníčková, a former skier and model, in 1977 – born and raised in Czechoslovakia, Ivana became a US citizen in 1988

Ivana and Trump were married for 14 years and have three children together: Donald Jr, Eric and Ivanka. The couple broke up amid reports of infidelity on Trump’s part. During their marriage, Ivana was involved in her husband’s business in varying capacities – running various hotels and casinos, and designing the interiors of properties.

In 2017, Ivana said that President Trump had made her an offer to be the ambassador to the Czech Republic. She said she turned it down because “it’s four years in Prague, so bye-bye to Miami, bye-bye to New York in spring and fall, bye-bye to Saint-Tropez in summer”.

Ivana published a book titled Raising Trump in 2017 about raising her children. “Donald might not have been the greatest husband to me, but he was a good father to the kids,” she wrote.

Ivanka Trump, Trump’s oldest daughter, is a senior adviser to her father

Named Ivana after her mother, she goes by her nickname, “Ivanka”. Ivanka, 38, attended Georgetown University for two years. She transferred to the University of Pennsylvania where she secured a degree in economics. Ivanka starting modelling as a teenager and walked the runway for Versace.

She’s also dabbled with helping the Trump Organisation in deals and negotiations as well as starting her own lifestyle brand – The Ivanka Trump Collection. After assuming her role in the White House, she stepped down from both the Trump Organisation and her fashion line. When Nordstrom, Neiman Marcus and others dropped her fashion line, citing poor sales, she shut down her brand in 2018. She's married to real estate developer Jared Kushner, who is also a senior adviser to the president. They have three children: Arabella, Joseph and Theodore.

Eric is married to television producer Lara Trump and has a son with her. They’re expecting a second child in August. In 2018, E News called them “the most normal, least controversial couple” in the Trump family. He has made media appearances on networks like Fox and CNN to defend statements made by his father.

Eric has been involved with his father’s 2020 re-election campaign, specifically with establishing a rapport with high profile donors and campaign finances.

Trump married Marla Maples in 1993 and separated after four years of marriage, according to a 1999 New York Post story

Their daughter, Tiffany, was born in October 1993. Two months later, the couple got married at the Plaza Hotel in New York City. Vanity Fair’s Gabriel Sherman wrote that “where Ivana was the austere European with royal aspirations, Maples was a beauty queen from the Bible belt”.

After separating from Trump in 1997, Maples raised Tiffany in California. Tiffany, now 26, graduated from Georgetown Law School in May 2020. Speaking to the New York Times in 2019, Marla said, “I’m not in the White House. I have friends on both sides. I will just walk in the middle. I’ll do everything I can to remind people that any type of anger or judgment can truly have such a negative impact on ourselves, and absolutely on our environment.”

According to a Brides story, Melania and Trump met when he was on a date with another woman. Guests at their wedding included Bill and Hillary Clinton. One of her most widely known efforts as the First Lady is the “Be Best” initiative focused on “major issues facing children today”.

The programme has been criticised for lack of proper policy or a path towards concrete legislation. In May 2020, CNN’s Kate Bennett wrote that “most of its accomplishments in terms of advancing funding for children’s issues under the banner of 'Be Best' come via partnerships with programmes that already exist within the federal government”.

The Washington Post correspondent Mary Jordan is publishing a book titled The Art of Her Deal that includes accounts of Melania renegotiating terms of her prenup after Trump's 2016 election win and a contentious relationship between with Ivanka.
