He was the third son of Richard William Randall and his wife Wilhelmina, daughter of the Russia merchant George Augustus Bruxner, born 6 March 1855 at Graffham.
[5] In 1883, as the Northern Pacific tracks pushed on west well past Bozeman, Randall arrived in the area with his younger brother Frank (Francis Henry), and a cousin Harry Lowndes.
[6] Returning to England, Randall married on 3 September 1884 Elizabeth FitzHerbert, known as Isabel, at St Peter's Church, Bournemouth, the officiant being his father.
[7][8] He financed the trip back to Holdenhurst by mortgaging the house he had purchased at Moreland to his uncle Leslie Randall.
The couple crossed the Atlantic first class in early October, took a train from New York via Chicago, and arrived at Moreland towards the end of the month.
[10] Isabel Randall published, as "I. R.", the book A Lady's Ranche Life in Montana (London, 1887), noted for its uncomplimentary remarks about American neighbours and customs, and spent a period back in England in 1887.
