In 1689 an 'Act for the Attainder of Divers Rebels, and for Preserving the Interest of Loyal Subjects' was passed in the Irish parliament. It listed the names of Irish Protestants considered by the government of James II to be disloyal to the King. Most of those listed were members of the landed gentry or freeholders. The names of those attainted (i.e. found guilty of treason) were published in 'The State of the Protestants of Ireland under the late King James's Government' by William King (Dublin, 1713).
For useful background to the Siege of Londonderry refer to this Wikipeida page
The Parliament, called in Dublin, by King James, 7th May, 1689, had no representatives from the counties of Derry, Donegal or Fermanagh; and as many Protestants from those counties were engaged in the defence of Londonderry, they are described in the Act as .of Donegal or Derry. In the subjoined abstract, from it, are the names and addresses of such of the attainted persons as appear in the Corporation Minutes or any of the Derry Diaries, as participators in the defence of Derry, Sligo, or of the Passage of the Bann.
Of course many more are in the Act than we can identify as being the same persons mentioned in those histories. If parties possessed of local information respecting them supply it to the Publisher, additions can be made to this abstract hereafter.
