The Rockefeller family (pronounced /ˈrɒkɨfɛlər/) is the Cleveland family of John D. Rockefeller (1839–1937) and his brother William Rockefeller (1841–1922). It is an American industrial, banking, and political family that originally came from Germany. It made one of the world's largest private fortunes in the oil business during the late 19th and early 20th century. This was mainly through the Standard Oil Company.
The family is also known for its long association with and financial interest in the Chase Manhattan Bank, now JP Morgan Chase. People see them as one of the most powerful groups inside the United States and are well connected to the banking industry. Their ancestor, Johann Peter Rockefeller, moved to North America in 1723 from what is today Westerwald, Rhineland-Palatinate, Germany.
