Townshend Mainwaring (16 March 1807 – 25 December 1883) was a British Conservative Party politician.
[1][a] Mainwaring married Anna Maria Salusbury, the eldest daughter of Colonel John Lloyd Salusbury of Galltfaenan Hall, in February 1837, at which time Mainwaring was living at Marchwiel Hall.
[6][7] He was one of the chairman of the National Eisteddfod of Wales when it was held at Ruthin in 1868,[8] days after sustaining severe injuries to his leg when his horse fell on him,[9] and was involved with other similar events, including that at Rhyl in 1863.
[b] An obituary noted his benevolent financing of the construction of a church, parsonage and schools in Trefnant, in memory of his father-in-law, as well as a convalescent home for men in Rhyl.
He was also noted to be a supporter of a women's home in Rhyl and of the same town's Royal Alexandra Hospital.
