Captain Sir John Norman Ide Leslie

Captain Sir John Norman Ide Leslie, 4th Baronet (1916 –2016), known locally as Jack Leslie, was the eldest son of Sir John Randolph Leslie, 3rd Baronet (known as Shane Leslie), and Marjorie Ide. He became the fourth baronet when his father died in 1971.

Educated at Downside School and Magdalene College, Cambridge, Leslie never married or had children. During World War II, he served as an officer in the Irish Guards during the Battle of France before being captured at Boulogne-sur-Mer. He then spent five years in POW camps.

After the war, he moved to New York City and later traveled around Europe, settling in Rome. At the age of 78 he returned to his family's homestead, Castle Leslie and traveled to Ibiza for his 85th birthday in 2001. 

He inadvertently revealed the wedding location of Sir Paul McCartney and Heather Mills by admitting to reporters it was to take place in Castle Leslie, but that it was "a secret". In January 2012, he appeared in the television programme Secrets of the Manor House, which discussed the Leslie family and Castle Leslie, among other manor homes. 

In 2015, he featured in the TV series Tales of Irish Castles. Leslie was presented with the Legion d'Honneur at the French embassy in Dublin on 9 November 2015.

A passionate beret wearer, Sir John had an interesting way of wearing his berets. Typically he would have the headband of his Basque beret folded outwards (visible) and usually a feather on it as decoration.
