(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
