He was the son of Francis Seymour, 1st Baron Seymour of Trowbridge, whom he succeeded in the barony in 1664. Francis had been a younger brother of William Seymour, 2nd Duke of Somerset.^{[citation needed]}

Prior to his ennoblement, Charles Seymour represented Great Bedwyn in the Short Parliament of 1640 and Wiltshire in the Cavalier Parliament from 1661 to 1664.^[1]

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.
