Broadhead was the eventual heir to estates in four counties, but in the decade after his father’s death in December 1820 he shared both his addresses with his mother. She was the sole beneficiary of the will of his father, who had sat from 1812-18 for Wareham and in 1820 as a Canningite paying guest for the pocket borough of Yarmouth, where Broadhead came in as his successor.
Broadhead used both surnames in correspondence in 1829, when he informed an antiquarian of his marriage, and formally resumed the exclusive use of the older patronym in 1842.
Brinckman died in February 1880 at his Windsor residence. In his will, dated 8 May 1875, he left numerous bequests and annuities to relatives and servants. The residual legatee was his eldest son, who inherited all his property. In a codicil dated 24 Dec. 1875, Brinckman doubled the settlement of £10,000 in railway stock on his youngest son Arthur, ‘a hardworking minister in the service of God’, as a mark of special favour. A local newspaper obituary eulogized him as ‘kind hearted and a most liberal supporter of the Windsor Royal Infirmary and Dispensary’, a charity he remembered in his will, along with the London Society for the Propagation of the Gospels in Foreign Parts.
