The baronetcy passed to the Captain's two sons in succession, and did them no good. The elder died insane, and the younger became eccentric, amounting almost to idiocy, and for 50 years was a figure of fun at the court of Windsor. He inherited a mere fragment of property, and that was soon exhausted, and Lord North, the Prime Minster, gave him a modest income and a place in the Garter homes of Windsor. He lived and died as Sir John Dineley, the 'Poor Knight of Windsor', his life and clothes being one of the curiosities of Windsor. He shopped in a great cloak, beneath which appeared thin legs in dirty stockings, and stalked upon pattens carrying a formidable umbrella. On state occasions he wore a costume of an earlier rieign, dirty and ridiculously worn. His diseased imagination believed he had recovered his lost fortune, and he went around approaching potential brides with a printed proposal of marriage, from 'Sir John Dineley, Baronet, of Charlton, near Worcester.
Twice yearly he attended the London theatres and Vauxhall, to find a bride, and great crowds came to see him - but none became Lady Dineley. He died in 1809, aged 80, and still a batchelor. The last of the Dineleys, the Rev. George Dineley, sold out at Peopleton and came to live in Worcester, at South Hayes, London Road.
