(Mental Floss) -- President-Elect Obama's mother-in-law will be moving to Washington with the first family, at least temporarily, his transition team has confirmed. Marian Robinson will be the latest in a line of presidential in-laws who, for good or ill, lived under the same roof as the president.
President Dwight Eisenhower and his mother-in-law, Elivera Doud, pose for pictures with some of the grandchildren.
Here are four stories that confirm the old truism: While America can choose its president, the president can't choose his in-laws.
1. Ulysses S. Grant and 'The Colonel'
You would think that the Civil War was settled at Appomattox, and no question of its outcome would have been raised in the White House of Ulysses S. Grant, who, after all, was the general who won the war.
But you would be wrong, because living with Ulysses and Julia Grant was the president's father-in-law. Colonel Frederick Dent (his rank seems to have been self-selected) was an unreconstructed Confederate, a St. Louis businessman and slaveholder who, when his daughter Julia went to the Executive Mansion early in 1869, decided to relocate there as well.
The Colonel didn't hesitate to make himself at home. When his daughter received guests, he sat in a chair just behind her, offering anyone within earshot unsolicited advice. Political and business figures alike got a dose of the Colonel's mind as they waited to meet with President Grant.
When the president's father, Jesse Grant, came from Kentucky on one of his regular visits to Washington, the White House turned into a Civil War reenactment. According to "First Families: The Impact of the White House on Their Lives", by Bonnie Angelo, Jesse Grant preferred to stay in a hotel rather than sleep under the same roof as the Colonel.
And when the two old partisans found themselves unavoidably sitting around the same table in the White House, they avoided direct negotiations by using Julia and her young son, named for the president's father, as intermediaries, Betty Boyd Caroli writes in "First Ladies": "In the presence of the elder Grant, Frederick Dent would instruct Julia to 'take better care of that old gentleman [Jesse Grant]. He is feeble and deaf as a post and yet you permit him to wander all over Washington alone.' And Grant replied [to his grandson and namesake], 'Did you hear him? I hope I shall not live to become as old and infirm as your Grandfather Dent.'" Mental Floss: 5 feisty first daughters
The Colonel remained in the White House -- irascible and unrepentant -- until his death, at age 88, in 1873.
2. Harry S Truman and the Mother-in-Law from Heck
Harry Truman and Bess Wallace met as children. He was a farm boy; she was the well-heeled granddaughter of Independence, Missouri's Flour King. When they married in 1919, Truman was a struggling haberdasher, and Bess's mother, Madge Wallace, thought Bess had made a colossal social faux pas. Until she died in 1952, Madge Wallace never changed her mind about Harry Truman. Her Bess had married way below her station.
Madge had plenty of opportunities to let her son-in-law know it. The newlyweds moved into the Wallace mansion in Independence, and the three lived together under the same roof until the end of Madge's life.
When Harry Truman was elected senator, "Mother Wallace," as Truman judiciously called her, moved with her daughter and son-in-law to Washington. In the family's apartment, she shared a bedroom with the Trumans' daughter, Margaret. And when Truman became president, she moved with them into the White House, where she cast her cold eye on the new commander-in-chief.
"Why would Harry run against that nice Mr. Dewey?" she wondered aloud, as Truman was fighting for his political life in the 1948 presidential race, according to "First Mothers" by Bonnie Angelo. And when Truman fired Gen. Douglas MacArthur for insubordination, Mother Wallace was scandalized. "Imagine a captain from the National Guard [Truman] telling off a West Point general!"
In December 1952, shortly before Truman's term ended, Madge Wallace died, at age 90. For the 33 years they lived together, she never called her son-in-law anything but "Mr. Truman" to his face. Mental Floss: Presidential siblings and the headaches they caused
3. Dwight D. Eisenhower and the Mother-in-Law of the Year
If Truman's story sounds like the set-up for a film noir, his successor's relationship with his mother-in-law might have been a Technicolor musical.
Elivera Mathilda Carlson Doud, Mamie Eisenhower's mother, was "a witty woman with a tart tongue," Time magazine wrote, and Dwight Eisenhower thought she was a hoot. "She refuted every mother-in-law joke ever made," Time wrote. There was no question that she would join her daughter and son-in-law in the White House.
Ike called her "Min," the name of a character in the Andy Gump comic strip. Ike and Min "constituted a mutual admiration society, and each took the other's part whenever a family disagreement would arise," said Eisenhower's son, John. The New York Times observed, "The president frequently looks around him sharply, and inquires, 'Where's Min?'"
Widowed shortly before Eisenhower became president, Min spent the winters in the White House and summers at her home in Denver. It was while visiting his mother-in-law's home that Eisenhower suffered a heart attack in 1955. Two years later, in failing health, Min returned permanently to Denver. She died in 1960, at age 82.
4. Benjamin Harrison and the Reverend Doctor
Benjamin Harrison's father-in-law, John Witherspoon Scott, bore a double title: "reverend doctor."
Scott was born in Pennsylvania in 1800, did post-graduate work at Yale and took a professorship in mathematics and science at Miami University, in Ohio. He was also a Presbyterian minister and an outspoken abolitionist. The reverend doctor was rumored to have shielded runaway slaves in his home as a stop on the Underground Railroad. Whatever the truth, Miami University dismissed him for his anti-slavery beliefs.
He accepted a post at Farmer's College, a prep school in Cincinnati, where he became a mentor of a student named Benjamin Harrison. During his visits to the Scott home, Harrison became friendly with the reverend doctor's daughter, Caroline.
Young Harrison spent so many evenings at the Scotts' home that he got the nickname "the pious moonlight dude," according to "The Complete Book of the Presidents" by William A. DeGregorio. He and Caroline were married in 1853 at the bride's house. The reverend doctor officiated.
John Witherspoon Scott later became a clerk in the pension office of the interior department. He gave up the position when Harrison was elected president in 1888. A widower since 1876, Scott moved into the White House with his daughter and their family.
It was the president's custom to lead the family in a half-hour of Bible reading and prayer after breakfast, Anne Chieko Moore and Hester Anne Hale wrote in "Benjamin Harrison: Centennial President." When the president was absent, his father-in-law took his place.
Caroline Harrison died in October 1892, two weeks before her husband lost the presidential election. Her father died the next month, at age 92. An obituary described John Witherspoon Scott as "a man of wonderful physical vigor, tall, broad chested and well preserved mentally." Mental Floss: The bizarre history of White House pets
