Sir Charles Leyshon Dillwyn-Venables-Llewelyn, 2nd Baronet (29 June 1870 – 24 June 1951) was a Welsh Conservative Member of Parliament (MP) who briefly represented Radnorshire in the House of Commons and served as Lord-Lieutenant of Radnorshire.
Following this marriage, the Llysdinam estate came into the family and Sir Charles assumed the additional surname of Venables.
He established a wildlife centre on the estate, today run by Cardiff University.
His daughter, Agnes Barbara Dillwyn-Venables-Llewelyn, married naval officer Cedric Holland on 15 June 1925.
He died five days before his 81st birthday in June 1951, last survivor of the 22 MPs who only served in the parliament of 1910.
