There are two notable contexts associated with the name Donner.Donner Party. The Donner Party, also known as the Donner–Reed Party, were American pioneers who migrated to California in a wagon train from the Midwest in 1846. Unfortunately, they became snowbound in the Sierra Nevada mountain range during the winter of 1846–1847. Some resorted to cannibalism to survive, consuming the bodies of those who had succumbed to starvation, sickness, or extreme cold. Historians consider this episode one of the most tragic events in California history and American westward migration.
