Levy-Lawson's family was Jewish. He married Harriette Georgiana Webster, daughter of
Benjamin Nottingham Webster, at Parish Church,
Kennington, Kent, in 1862. They had three children together,
Harry (later Viscount Burnham), William and Edith. Lady Burnham died in 1897. It is also believed that Levy-Lawson may have been the natural father of the author
Reginald Turner, although Turner's father may have been another man of the Levy-Lawson family. Lord Burnham's love of
pheasant shooting resulted in him enjoying a close relationship with King
Edward VII, his son, King
George V, and his son King
Edward VIII, with King George paying yearly visits to him at his home, the 4,000 acre estate
Hall Barn. On 18 December 1913, it was recorded by the Prince of Wales himself – later
King Edward VIII – that he and his father King George had "shot over a thousand pheasants in six hours – about one bird every 20 seconds". Altogether, 3,937 pheasants were killed. While it has been said that the shoot was not a slaughter and that very respectable birds were presented to the Guns, on the train journey home, the Prince of Wales noticed that the King was unusually quiet, his silence eventually broken when he famously said: "Perhaps we overdid it today." Lord Burnham died on 9 January 1916, aged 82, in
Forest Gate, London, and was succeeded in the barony by his eldest son Harry. He was buried in
Beaconsfield,
Buckinghamshire. ==Arms==
