White was descended from a noted family of
The Pale. His father, James White of
Waterford, who was the steward of the
earl of Ormond, had been poisoned while in London, as was the earl, in 1546. Nicholas owed his early advancement to Ormond's influence: in recognition of James's loyalty, the earl left £10 for the boy's education at the
Inns of Court. White entered
Lincoln's Inn in 1552, and he was
called to the Bar in 1558; during the course of his studies he was a tutor to the children of
Sir William Cecil, later Lord Burghley. He then returned to Ireland and was elected a member of the
Irish Parliament for
County Kilkenny in 1559. He was
justice of the peace for
County Kilkenny in 1563 and in the following year was named
Recorder of
Waterford. In 1567 he bought
Leixlip Castle as his base near Dublin. White may have published an English
translation of the
Argonautica in the 1560s, but no copy has survived. He had stayed in correspondence with Cecil, and became an important confidant of his and thus an influential commentator on Irish affairs. In 1568 he was given the right to travel to England and had a notable interview with
Mary, Queen of Scots, at
Tutbury Castle in February 1569. They discussed her use of the English language and her needlework. White noted her "pretty Scottish speech" and recorded the motto embroidered on her cloth of estate, "En ma fin est mon commencement", My End is in My Beginning. She mentioned that he was going to Ireland, and White said that the chiefest trouble of Ireland proceeds from the actions of the
Earl of Argyll. On 4 November 1568 Elizabeth, who in the early stages of his career thought well of him, appointed him seneschal of
Wexford and constable of Leighlin and Ferns, replacing the disgraced adventurer
Thomas Stukley. He retained the office until 1572, concluding his tenure with the pursuit of the rebels, led by
Fiach McHugh O'Byrne, who had murdered his son-in-law Robert Browne. White established his estate at White's Hall, near
Knocktopher,
County Kilkenny, and also acquired
Dunbrody Abbey,
County Wexford, and the Castle and St Catherine's Priory at
Leixlip,
County Kildare. ==Master of the Rolls in Ireland==
