What is the name of the Queen's first private secretary in the series?

Tommy Lascelles is the name of the Queen’s first private secretary depicted in The Crown. His full name was Sir Alan Frederick Lascelles, but “Tommy” was the familiar name by which he was widely known.

Lascelles served as private secretary to King George VI from 1943 and continued in the role when Elizabeth became queen in 1952. He remained her private secretary until 1953, making him the first person to hold that position during her reign. Pip Torrens portrays him in the series.

The main source of confusion is that several royal aides hold similar offices. Michael Adeane succeeded Lascelles as the Queen’s private secretary, while Martin Charteris served as assistant private secretary before later becoming private secretary himself. Alan Lascelles is not a different person from Tommy Lascelles; it is his formal name, so both names refer to the same historical courtier.
