Elizabeth “Lily” Mernin, an Irish intelligence agent known as the “Little Gentleman” or “Lt. G.,” dies in Dublin on February 18, 1957.

Mernin is born in Clanbrassil Street, Dublin, on November 16, 1886. Her parents are John Mernin and Marianne “Mary” (née McGuire). She has one sister, May. Her father is a baker and confectioner of Dorset Street, Dublin. After his death when Mernin is young, the children are raised by his family in Dungarvan, County Waterford.

In the 1910s, Mernin works as a typist in a number of Dublin companies, and by 1914 she is a shorthand typist in Dublin Castle at the garrison adjutant’s office. She is a member of the Keating branch of the Gaelic League, and through this her cousin, Piaras Béaslaí, introduces her to Michael Collins in 1918. From 1919 she begins working for Collins as an intelligence agent. She uses her position in Dublin Castle to obtain important documents and, in 1920, intelligence on British intelligence officers and the auxiliary police.

Under the alias of “Little Gentleman” or “Lt. G.,” Mernin is one of Collins‘a most important agents, so much so that many believe the Little Gentleman is a British intelligence officer. One of the most important contributions she makes is identifying the homes of British intelligence officers who are later killed on Bloody Sunday, November 21, 1920, by Collins‘s Irish Republican Army (IRA) unit The Squad. She aids Frank Saurin and Tom Cullen in identifying senior British agents in Dublin, typing secret reports for Collins in a room in 19 Clonliffe Road.

In February 1922, Mernin is discharged from the British service, taking up a position as a typist in the Irish Army from July 1922 until February 1952, when she retires. She works primarily at Clancy Barracks. She is awarded a military pension for her service from 1918-1922, and her statement is held in the Bureau of Military History in the Military Archives.

Mernin never marries, although she gives birth to a son in London in June 1922, with some evidence suggesting Béaslaí is the father. She lives at 167 Mangerton Road, Drimnagh. She dies at the age of 70 on February 18, 1957, in Dublin.
