Which US president grew up as an orphan?

1. He was the first president born west of the Mississippi River. Herbert Clark Hoover was born on August 10, 1874, in a two-room, whitewashed cottage built by his father in West Branch, Iowa, a small prairie town of just 265 people. The future president did not cross east of the Mississippi River until he was 22 years old.
2. Hoover became an orphan at age 9. When Hoover was 6 years old, his father died of a heart attack while suffering a bout of pneumonia. A little more than three years later, Hoover’s mother, Hulda, died from pneumonia and typhoid fever, which left young “Bertie” and his older brother and younger sister parentless. The three children were separated to live with Hulda’s various relatives. When Hoover was 11, he was put on a westbound Union Pacific train to live with Hulda’s brother John Minthorn in Newburg, Oregon.
