Some of Shane's surviving son's were given sizable land after the flight of the earls that had previously belonged to Hugh O'Neill. Henry was given land in Orior, Con was given the estate of Clabbye, and Brian was given land in Clinawly, Fermanagh. Brian's son Edmond was granted control of Lisdawericke, Megin, Cnoghan, Tollohiny Dirrilghta, Knockmcgallcrum &amp; Gortnesillagh. Henry's son Cormocke (Cormac) was given land. This spread the clan throughout the province and lessened their influence. Brian, son of Hugh, the Chief of the McShane O'Neills led the clan in the 1642 Rising, the Irish Confederate Wars, and fought against Oliver Cromwell's Army through the death of his 2nd cousin Owen Roe O'Neill in 1649 and the victory of Cromwell in 1653. Brian remained in Spanish exile until 1666. Two decades later, his son the new Chief, Brian Og (the Younger) led the clan in service of the O'Neill regiments supporting King James II. After the defeat of the Jacobite forces, the family was "attainted" as Irish rebels in 1693, and Brian "Og" left with the Army of King James II and went into exile in France. The eventual heir, Owen McHugh O'Neill, completely dropped any association with the O'Neill name, and just took McShane as a surname due to the Irish Penal Laws, in an attempt to hold his father's small estate.
