Lynskey was born in Knotty Ash, Liverpool, the son of solicitor George Jeremy (1861-1921) who had himself been born in Ireland and sat on Liverpool City Council as alderman representing the Irish National League. He entered his father"s practice as a solicitor in 1910, marrying Eileen Mary Prendiville in 1913.
Lynskey had three younger brothers and two sisters and was educated at Saint Francis Xavier"s College then at the University of Liverpool. He earned an Bachelor of Laws (1907) and Master of Laws (1908).
The couple had two daughters. In 1920 Lynskey took up the profession of a barrister, being called to the bar by the Inner Temple. He practised on the northern circuit, building up one of the largest provincial practices of the time and becoming a KC in 1930.
David Maxwell Fyfe, a future prosecutor at the Nuremberg Trials was one of his pupils and praised Lynskey"s geniality and conviviality.
He became a bencher of the Inner Temple in 1938 and a judge of the Salford Hundred Court of Record in 1937. In 1944 a provincial barrister educated at a redbrick university with little exposure to the London bar or specialist practice, no matter how successful, was an unusual appointment for a High Court judge.
However, he was appointed to the King"s Bench and became an effective but unfailingly courteous judge in criminal trials at various assizes around England and Wales. In 1945, he sat with Lord Chief Justice Lord Goddard and Mr Justice Humphreys in the Court of Criminal Appeal in William Joyce"s appeal against his conviction for treason during World World War World War II The court rejected Joyce"s appeal.
