Fahavane was listed as common or unprofitable land in 1641 and again in 1670 after the Down survey. Most surrounding townlands were owned by the Stack family, whose name is common to the area. Stack family members lost their land to Henry Ponsonby, a
Cromwellian soldier, because of their support for the
Irish Rebellion of 1641 and the
Catholic Confederation. In modern history, the most famous people from Fahavane were George O'Shea and
Stephen Fuller, former
Republican soldiers. Fuller later became the
Teachta Dála for
North Kerry representing
Fianna Fáil in the 9th and 10th
Dáil Éireann. He was the sole survivor of the notorious
Ballyseedy massacre of 7 March 1923, where he, O'Shea and seven other Republican prisoners of the
Free State army were tied standing in a circle around a
land mine which was prepared and detonated by officers of the
Dublin Guard. O'Shea and Timothy Twomey, also from the Kilflynn civil parish, are buried in the Republican plot in Kilflynn. ==Religion==
