Spencer family

The Spencer family is one of Britain's preeminent aristocratic families. Over time, several family members have been made knights, baronets, and peers. Hereditary titles held by the Spencers include the dukedom of Marlborough, the earldoms of Sunderland and Spencer, and the Churchill viscountcy. Two prominent members of the family during the 20th century were Sir Winston Churchill and Diana, Princess of Wales.
