Lane-Fox was the son of James Fox-Lane, of Bramham Park, West Yorkshire, by the Honourable Marcia Lucy, daughter of George Pitt, 1st Baron Rivers.
They had five children: The family received rents of land and buildings (the leases commencing between 1836 and 1843) for the duration of the lives of three of Lane-Fox's children, assigned by his cousin Francis D'Arcy-Osborne, 7th Duke of Leeds, mainly in the Cornish parishes of Breage, Camborne, Germoe, Ludgvan, St Erth and Wendron — which brought annual income of c. £5,000 (equivalent to £675,000 in 2023).
On Elizabeth's death these freehold reversions (or near-equivalents) reverted to the ownership of the then-heir of the senior branch, George Osborne, 9th Duke of Leeds.
Charlotte Alice Fox Olding was born at 11 Burton Street London and was Baptised eleven years later (5 August 1861) as Alice Florence Marion Fox at St Saviour Jersey by The Rector William Corbet Le Breton who was the Father of Lillie Langtry - The Jersey Lily.
There are no marriage records for Sackville Walter Lane Fox and Charlotte Susannah Olding.
