The Rev Ranulph Dacre TREVOR-ROPER was the youngest son of Dacre TREVOR-ROPER (12 I 1839 - 18 VII 1922) and his wife (married 25 VIII 1875), Louisa WANKLYN (c.1843/4 - 29 IV 1931), while his wife, Joan Fraser WOODCOCK, was the granddaughter maternally of Louisa's brother William Trevor WANKLYN (1837 - 28 VIII 1904) and his wife (married 16 VII 1862), Mary Anne FFARINGTON (1839 - 8 VII 1887).
