[Answer] Which first name is unique among U.S. First Ladies?

Step 1 : Introduction to the question "Which first name is unique among U.S. First Ladies?"

...The only U.S. First Lady named Lucy was Lucy Hayes, wife of President Rutherford B. Hayes. Serving from 1877 to 1881 during the post–Civil War Reconstruction era, she was known for her strong moral convictions and for supporting her husband’s decision to ban alcohol from White House functions, earning her the nickname “Lemonade Lucy.” By contrast, Abigail (Adams and Fillmore), Edith (Roosevelt and Wilson), Martha (Washington and Jefferson Randolph), and Elizabeth (Monroe and Ford) all appear more than once in First Lady history.

[Answer] Which letter starts the fewest words in the English language?

Step 1 : Introduction to the question "Which letter starts the fewest words in the English language?"

...Try naming five words that begin with the letter X. Xylophone, X-ray…not so easy, right? You may want to stop because the Oxford English Dictionary only lists a mere 400 words that begin with the letter X. In Noah Webster's Compendious Dictionary, published in 1806, just one entry appeared under X: xebec, a type of Mediterranean sailing ship. When Webster released his more expansive American Dictionary of the English Language in 1828, that total had grown to only 13. Over time, the number steadily increased—largely through scientific and medical terms—eventually reaching the roughly 400 recognized today.

Step 1 : Introduction to the question "Abraham Lincoln is widely credited with popularizing which now-common pet name after giving it to his dog?"

...President Abraham Lincoln owned a yellow mixed-breed dog named Fido during his years in Springfield, Illinois. At the time, the Latin-derived name—meaning “faithful”—was not yet a generic label for dogs. Lincoln’s national prominence helped propel the name into widespread use, and “Fido” eventually became shorthand in American culture for the archetypal family dog. Although names like Rover and Spot later became equally stereotypical pet names, it was Lincoln’s beloved companion that helped turn “Fido” into a cultural staple.
