The adorable love stories of 11 presidents and their first ladies

John and Abigail Adams were partners, through and through. Even when work and war separated the couple, they sought to stay in contact.

In "First Ladies," historian James Taylor estimated that the pair wrote around 1,170 letters to one another, penning messages around once or twice a week.

"They were partners in everything he did. ... he writes to her thanking her for being a partner in the activities," he said.

The pair's trove of letters reflects their habit of teasing one another, and an affectionate side to their marriage. Business Insider previously reported that Adams referred to his wife as "Miss Adorable" and "Diana," after the Roman goddess of the hunt and the moon.

Abigail called him Lysander — referencing the Spartan War hero — and "my dearest friend."

In 1794, Dolley Payne was just about the most eligible bachelorette in all of Philadelphia.

The young mother had tragically lost her first husband, one son, her mother-in-law, and her father-in-law in a 1793 yellow fever epidemic. She had little in the way of financial resources.

Still, the 26-year-old Payne was considered beautiful and charming, and attracted a number of suitors.

One such admirer was 43-year-old politician James Madison, who fell hard for the widow when he caught a glimpse of her on the streets of Philadelphia.

The two had little in common. Dolley was vivacious, social, and confident. Madison was slight, cerebral, and a touch awkward — he once reportedly refused to go outdoors after misplacing his hat.

Still, the couple had a lot of famous figures rooting for them. Future vice president Aaron Burr — who attended Princeton with Madison — may have formally introduced them.

And, as historian Catherine Allgor recounted in the book "First Ladies," the courtship received a glowing endorsement from Martha Washington.

The pair wed in 1794. Over the years, their bond only grew stronger.

"As the marriage went on, she fell deeply in love with James, and James got over his infatuation and loved her deeply as well," Allgor said.

March 4, 1829 must have been a truly bittersweet day for Andrew Jackson.

He had defeated incumbent president and longtime rival John Quincy Adams and ascended to the White House. But, by his own feeling, the contentious race for the presidency had cost his wife Rachel her peace of mind, health, and, ultimately, her life.

And so, as Washington D.C. celebrated his victory, the president mourned his spouse, who had died on December 22 of the previous year.

The trouble that would plague Rachel Jackson during the election of 1828 had been simmering for years before her husband decided to run for office.

In "First Ladies," historian Patricia Brady said that, before she met Jackson, Rachel was "married very unhappily to a man who treated her badly."

Then she met Jackson, who was renting a room at one of her mother's properties.

"All his life, Jackson... couldn't bear to see women mistreated," Brady said.

Jackson and Rachel fell in love and eloped to Natchez.

The couple was close, and Brady described Rachel as Jackson's "touchstone."

Meanwhile, Rachel's first husband Lewis Robards proceeded to file for divorce in Virginia.

The Jacksons assumed that was the end of the story, but years later it was revealed that Robards had failed to follow the proper instructions when filing.

So technically, Rachel's marriage to Jackson was bigamous. Jackson's rivals seized upon the story in the 1828, decrying Rachel as an adulteress.

The stress took its toll on Rachel. Her health declined, and she ultimately succumbed to a heart attack a month after the election.

According to WNPT, Jackson initially "refused to believe she was dead and asked servants to lay blankets across the dining room table in case she woke up and needed comfort or warmth."

She was buried on Christmas Eve, dressed in the white gown and shoes she had planned to don at the inaugural ball.

By all accounts, Andrew Johnson had a close relationship with his wife Eliza.

In "First Ladies," historian Jacqueline Berger noted that the president's days "seemed to revolve around Eliza," who he always consulted before heading off to work.

The couple met as teenagers in Greeneville, Tennessee. Berger recounted a popular story of their first meet-up. Eliza was reportedly chatting to some friends outside the school one day when she spotted newcomer Andrew Johnson rolling into town for the first time.

Berger said Eliza joked that the young man was her "beau." And sure enough, 16-year-old Eliza and 18-year-old Andrew Johnson struck up a courtship and wed shortly afterward.

Later on, Eliza would teach her new husband how to read and helped him run their tailor shop.

Who knew that Ulysses Grant had a romantic side?

The future president met his future wife Julia through her brother, his fellow West Point student Fred Dent.

According to the Smithsonian, the two read poetry and rode horses together, and Grant even built her a small, yellow coffin after her pet canary died.

Grant's military obligations would ultimately separate the pair for years during the Mexican-American War. FirstLadies.org reported that, after Grant left to report for duty, Julia allegedly dreamed that he would return in civilian clothes and propose.

He did just that, and the two went on to correspond for four years.

For Grant, the messages were a lifeline. According to the Smithsonian, one of Julia's letters contained two dried flowers, "... but when Grant opened it the petals scattered in the wind. He searched the barren Mexican sands for even a single petal, but in vain."

In response, he sent her a wildflower from the banks of the Rio Grande, according to the Washington Post.

The pair wed in 1848. Grant's abolitionist relatives refused to attend the ceremony, since Julia's family owned slaves.

In "First Ladies," historian William Seale said that Julia was supportive of her husband during his presidency, but wasn't afraid to criticize him in private.

The marriage was by all accounts happy, but Seale noted that Julia often fretted about her husband's skyrocketing fame, due to her lazy eye.

She looked into having it fixed but despaired after learning that the condition could not be corrected. According to Seale, when Grant learned what she had been doing, he told her "that he had fallen in love with her the way she was."

In "First Ladies," historian Kathleen Dalton recounted how future husband and wife Theodore and Edith Roosevelt were effectively raised together.

They both grew up around Union Square in New York City. They shared tutors, swapped books, and played together. Edith became close friends with Theodore's sister Corinne, as well.

However, Dalton said that their close relationship took a hit in their teens, after a mysterious quarrel. Roosevelt went on to attend Harvard and marry Alice Hathaway Lee.

After giving birth to the couple's daughter Alice, Lee died on the same day that Roosevelt lost his mother, a "tragedy that broke his heart," according to Dalton.

The grieving widower eventually turned to his childhood friend for comfort. They began covertly courting one another, until newspapers broke the news of their engagement and Roosevelt had to loop in his family.

According to Dalton, Roosevelt could be an "inconsiderate" and forgetful husband at times. However, she added that "Theodore Roosevelt adored Edith Roosevelt and she was devoted to him."

According to historian Lewis Gould's interview in "First Ladies," William and Helen Taft's lives began to intersect as they grew up in Cincinnati.

After the future president returned from Yale, the two began to court, venturing out to beer halls together.

"He was much more smitten with her originally than she was with him," Gould said. "He proposed, but she rejected him, which was standard in those days; the woman never accepted the proposal right off."

Helen Taft went on to become an active first lady, spearheading the planting of cherry trees in Washington D.C. Tragedy struck the couple in 1909, when a seizure left Helen unable to speak.

Gould said her husband coached her in the White House, helping her to regain her speech.

Believe it or not, Calvin Coolidge's first encounter with his wife Grace is a scene straight out of a romantic comedy film.

According to the Coolidge Foundation, Grace was working at the Clarke School for the Deaf in Northampton, Massachusetts. One day in 1903, while watering flowers near a neighboring boardinghouse, she caught a glimpse of a young man shaving in the mirror. He was dressed in long underwear and a hat.

Grace laughed at the odd sight. The young man — future president Calvin Coolidge — turned around. The two began courting shortly afterward.

And, as they say, the rest is history.

According to "First Ladies," historian Cyndy Bittinger said that the couple was a true case of opposites attracting. "Silent Cal," as he became known during his presidency, was quiet and thoughtful, while Grace was a vivacious and fun-loving White House hostess.

However, both Calvin and Grace shared a wry sense of humor and a love of animals.

Harry and Bess Truman were more than just close.

"He just didn't function with quite as much vigor when Bess wasn't near," historian Nicole Anslover said in the book "First Ladies."

In a twist of fate, the two attended Sunday school together as young kids. Bess reportedly didn't remember much of her future husband, but "Harry always spoke of the girl with the beautiful blue eyes and the long golden curls, and he claims that he fell in love with her that day," Anslover said.

"As far as we know, he never did look at another woman," she added.

Despite the fact that Bess occupied a higher social status than Harry, the two began courting. Truman passively proposed for the first time in a letter in 1913, asking Bess: "If I bought a ring, would you wear it on your left hand?"

She didn't respond, but they kept seeing one another. Then WWI broke out, interrupting their romance. Truman carried his beloved's picture throughout the conflict. The Trumans finally wed in 1919.

Ronald Reagan is remembered as a president who had a significant impact in the twilight years of the Cold War.

So it's ironic that he met the love of his life thanks to a communist scare in Hollywood.

His future wife Nancy — then known as Nancy Davis — found her named listed on a blacklist. The situation turned out to be a case of mistaken identity — a different Nancy Davis was suspected of harboring communist sympathies.

Nonetheless, Nancy ended up scheduling a meeting with Screen Actors Guild president Ronald Reagan to resolve the issue.

The 1949 meeting morphed into dinner, which then transitioned into a relationship. The couple wed in 1952.

In "First Ladies," historian Judy Woodruff said that Nancy was a protective and highly influential figure in her husband's inner circle, adding, "It was a remarkable partnership. It was a strong marriage. Ronald and Nancy Reagan loved each other deeply."

Barack and Michelle Obama's marriage would have never happened had she followed her initial instinct to avoid workplace romances.

Long before her time in the White House, Michelle was her future husband's mentor at the law firm Sidley Austin LLP.

Ultimately, she decided to give him a chance.

According to "First Ladies," historian Liza Mundy said that Obama was "taken" with his mentor and that colleagues "could tell that something was developing" based on the number of times they'd witness the young lawyer perched on Michelle's desk in the late afternoon.

The first date didn't get off to an auspicious start. According to David Mendell's "Obama: From Promise to Power," Michelle also thought Obama sounded "too good to be true" at first.

She was also unimpressed when he showed up to the date in a "bad sport jacket" with a "cigarette dangling from his mouth."

"I thought: 'Oh, here you go. Here's this good-looking, smooth-talking guy. I've been down this road before,'" she told Mendell, according to the Washington Post.

Barack managed to win her over, though. They went out walking, and later caught a screening of Spike Lee's "Do The Right Thing," the Telegraph reported.

At the end of the date, the couple reportedly had their first kiss outside a Baskin-Robbins at 53rd and South Dorchester in Chicago. The spot is now marked by a plaque commemorating the event, according to Atlas Obscura.
