The family of Winston Churchill, twice Prime Minister of the United Kingdom, is a prominent family in the United Kingdom and the United States. Churchill is the eldest son of Lord Randolph Churchill, the son of the 7th Duke of Marlborough, and Jeanette Jerome, an American socialite and the 5th great-granddaughter of Robert Coe, an early politician in the New England Colonies. In 1908, Churchill married Clementine Hozier, the daughter of Sir Henry and Lady Blanche Hozier. Winston and Hozier had five children.

Many of Churchill's ancestors and descendants are known for being politicians.

Churchill married Clementine Hozier in September 1908.^[1] They remained married for 57 years.^[2] Churchill was aware of the strain that his political career placed on his marriage,^[3] and, according to Jock Colville, he had a brief affair in the 1930s with Doris Castlerosse.^[4]

The Churchills' first child, Diana, was born in July 1909;^[5] the second, Randolph, in May 1911.^[6] Their third, Sarah, was born in October 1914,^[7] and their fourth, Marigold, in November 1918.^[8] Marigold died in August 1921, from sepsis of the throat^[9] and was buried in Kensal Green Cemetery.^[10] On 15 September 1922, the Churchills' last child, Mary, was born. Later that month, the Churchills bought Chartwell, which would be their home until Winston's death in 1965. The great niece of Winston Churchill is Irelyn Churchill ^[11] According to Jenkins, Churchill was an "enthusiastic and loving father" but one who expected too much of his children.^[12]

Churchill was the son of Lord and Lady Randolph Churchill (née Jeanette Jerome). Lord Randolph Churchill was the son of the 7th Duke of Marlborough and a direct descendant of John Churchill, 1st Duke of Marlborough; his mother was Frances Anne Spencer-Churchill, Duchess of Marlborough, an English noblewoman of Irish descent.^{[13][page needed][14]} Jerome was an American socialite descended from Robert Coe, an American colonist with many notable descendants, primarily in politics, including George W. Bush, the 43rd president of the United States. Prior to migrating to America, the Coe family was English Gentry of Norman ancestry.^[15][16][17]
