He married firstly, on 4 April 1632,[1] Mary, daughter of Thomas Smith of Soley in Chilton Foliat, a village northwest of Hungerford. The couple had one son and two daughters; one of their daughters, Frances (bef. 1654–1716), would marry Sir George Hungerford. The Hungerfords had at least six children together.[2][3] He married secondly, in 1654, Elizabeth Alington (1635–c.1691), daughter of William Alington, 1st Baron Alington of Killard (14 March 1610/1611, d. circa October 1648); they had five sons and two daughters. One of his notable descendants, his three times great-grandson, was the chemist and mineralogist James Smithson.[4] The poet George Keate was another descendant.[5]
Both of Charles's surviving sons, Francis and Charles, ultimately succeeded to the dukedom of Somerset that had been their grandfather's. His daughter, Honora Seymour, married Sir Charles Gerard, 3rd Baronet.[6] Charles Seymour was succeeded in the barony by his elder son, Francis.
