Thepresident’s childrenare often seen as American royalty.

Here are some of the weirdest relationships that presidents' children have had throughout history.

Trump siblings

I cannot possibly do both."

Fourteen years older than Alice, Congressman Nicholas Longworth was known to lovewomen and whisky.

And yet, the couple were said to berelatively happy together.

Teddy Roosevelt

They stayed married untilLongworth’s deathin 1931.

She wascriticalof her father’s political policies and didn’t share her parents' conservative style.

Even before her marriage, Davis was unlucky in love.

Patti Davis

“I went for men who were destined to hurt me emotionally,” she toldPeople.

Mary entered into, and later broke, an engagement with the Adams' oldest son, George.

Back in the late ’60s, he was engaged to Cathryn Lee Wolfman.

John Quincy Adams

The two met during college when Bush was studying at Yale and Wolfman was at Rice.

Still, the engagement (and their breakup) made headlines for other reasons.

Wolfman came from a Jewish family, while Bush was a devout Methodist.

George and Laura Bush

While the two may seem to make a good match now, the high-profile couple had a rocky beginning.

When they first met, 26-year-old Hager was actually George W. Bush’s employee, according toThe Washington Post.

I hate to have to be the one to say it on television.

Jenna Bush

But he’s a very nice young man" (viaThe Washington Post).

Yes, that’s right, there’s an industry for ping-pong.

In anObserverprofilefrom 2009, Raharinosy’s business partner said, “Franck can’t be stopped.

Bush family

Not surprisingly, the relationship didn’t last.

However, he was also a known drinker, gambler, and womanizer.

This caused much concern, especially after Martin Van Buren waselected president.

Martin Van Buren

Before dating Grace, Ivanka was linked withLance Armstrong.

A source toldPeopleback in 2006 that the two went on several dates, but apparently nothing came of it.

“I have tremendous respect for Lance and all he has accomplished,” Ivanka toldPeople.

Ivanka Trump

“That said, we are just friends.”

However, Ivanka never confirmed this, and a source close to her toldE!

Newsthat “this story is not true.”

Donald Trump Jr.

“Aubrey fell for him hard.”

But what if the happy couple consists of not one, but two presidential offspring?

In fact, only15 other couplesin U.S. history had done it.

Nixon with Daughter Julie

However, Julie refused the opportunity.

Instead, they wed in a nondenominational church in New York City.

In 2018,The Washington Postreported that the two were still married after 50 years.

Woodrow Wilson’s daughter Nellie

Despite these hurdles, Wilson and McAdoo became the12th coupleto be married in the White House in May 1914.

However, the two eventually called it quits and divorced in 1934.

One of his former loves was actress Daryl Hannah.

JFK Jr.

Interestingly, Hannah wasn’t the only girlfriend Onassis didn’t approve of.

U.K. native Shand introduced Kennedy to a fine-art program in London, and she enrolled.

When Kennedy arrived in London, she found that Shand was with another woman: American actress Barbara Trentham.

Caroline Kennedy

Shand, however, soon broke it off with Trentham, and he and Kennedy started dating.

According toAmerican Legacy, Kennedy was supposedly in love with Shand.

At the end of her studies, Kennedy finally returned home, and she and Shand broke up.

President James Monroe

While her wedding was certainly noteworthy, Maria’s choice in husband was perhaps an odd one.

But it was the wedding itself, not the couple, that would cause scandal.

This was seen as a slight and caused a social scandal in Washington.

Hunter Biden

After just three months of dating, Kathleen became pregnant, and the two married in 1993.

“We were sharing a very specific grief,” Hunter toldThe New Yorker.

“I started to think of Hallie as the only person in my life who understood my loss.”
