Just before his departure in March 1667 to take up the government of Barbados, William Willoughby, 5th (CP 6th) Baron Willoughby of Parham, wrote to the king asking him to take care of ‘the good breeder (my good wife) I leave behind, who hath brought your Majesty seven he subjects such as I dare own’.
Like his elder brothers, Charles spent the period before coming to the title helping to administer Barbados and in May 1673 he, with his brother John, had been made executor of his father’s will on the island.
Willoughby of Parham died in early December 1679, during the long prorogation of the second Exclusion Parliament. At his death the male line of his grandfather William Willoughby†, 3rd Baron Willoughby of Parham, became extinct. The 77-year-old son of the youngest son of the 9th baron’s great-great-grandfather Charles Willoughby†, 2nd Baron Willoughby of Parham, thereupon claimed the title and was summoned to the first meeting of the second Exclusion Parliament in October 1680 by writ. In the mid-eighteenth century, when it was discovered that the barony had passed to the wrong branch of the Willoughbys, this writ was retrospectively considered to have established a new creation of the title.
