Abney-Hastings was the elder son of General Sir Charles Hastings, 1st Baronet, by the daughter and heir of Thomas Abney Esq.

He was born in 1792, probably in Willesley[1] and succeeded his father in 1823, assuming, after his maternal grandfather, the additional name of Abney before that of Hastings, by Royal Licence 1 December 1823.

Charles' brother, Frank Abney Hastings, who might have inherited the title or fathered an heir, died a hero in 1828 at Zante.

[4] By a deed of settlement executed about 1846 the Blackfordby and Packington estates of Sir Charles passed to Henry Rawdon-Hastings, 4th Marquess of Hastings.

Willesley Hall and its estate were left to Lady Edith Maud Rawdon-Hastings, later Countess of Loudoun,[1] the Marquess' eldest sister and wife of Charles Frederick Clifton Esq.
