[1] Neville had a brother who died young, and a sister, Isabel, who married firstly, Sir Robert Plumpton, and secondly, Lawrence Kighley, Esq.

[4] As a young man, Westmorland was among those who attended King Henry VIII at the Field of the Cloth of Gold in June 1520 and at his meeting with Emperor Charles V at Gravelines in July.

In 1522–23 Westmorland saw military service on the Scottish border, where he was knighted in the latter year by Thomas Howard, then Earl of Surrey.

He continued to serve on the northern border, being appointed Deputy Captain of Berwick and Vice Warden of the East and Middle Marches from October 1525 to September 1526 under the King's illegitimate son, the Duke of Richmond.

[6] On 13 July 1530 Westmorland was among those who signed the letter to Pope Clement VII urging the annulment of the king's marriage to his first wife, Catherine of Aragon.

[citation needed] He again saw military service in the north when in June and July 1535 he was among those charged with suppressing disorders in Northumberland, Cumberland, and Westmorland.

He refused an appointment as Warden of the East and Middle Marches at this time, allegedly because his men supported the rising.
