  John was born the eldest son of Patrick de Courcy and Mary FitzGerald. His father was the 20th Baron Kingsale (also counted as the 19th or the 15th). His father's family, the de Courcys, were Old English and claimed descendence from John de Courcy, who had arrived in Ireland in 1176.
  
  His mother was a daughter of John Oge FitzGerald of Dromana. Her eldest sister, Helen (or Ellen) was the wife of his uncle Gerald, the 19th Baron Kingsale. The FitzGeralds of Dromana were Old English like the de Courcys. They were a cadet branch of the FitzGeralds of Desmond that started when Gerald FitzGerald, the second son of James FitzGerald, 6th Earl of Desmond (d. 1462) was given Dromana as an appanage.
  
  His parents married when his father was already 48 years old but had 23 children. However, only seven seem to be known by name.
