Chapter 1 WHIG AND TORY Sovereigns - William III and Mary II.
Years-1690 to 1702

Eighteen months later, in the summer of 1695, when the whigs secured a further advantage by the dismissal of the two tory lords justices, and the conversion of the whig one, Lord Capel, insto a lord deputy, an attempt was made to leaven the toryism of the bench, and Reynell anad Hartstonge, who had been dismissed by James for favouring Protestants, now found themselves dismissed by William for favouring Roman Catholics. The two new judges, Nehemiah Donnellan and Robert Doyne, whom these dismissals brought upon the bench, were both members of the Irish Bar, the former being prime serjeant and the latter a king's counsel, and as they had both sat in the Irish house of commons, where they had presumably given satisfactory proof of their whiggery, which afterwards appeared, however, to be no more than skin-deep. They were also, strange to say, both of Celtic origin, Donnellan having the same descent as Charles the Second's chief justice of the name, of whom he was son by his second marriage, and Doyne tracing his descent from Irish chieftains. (Footnote: Burke's Landed gentry of Ireland, under Doyne of Wells) Although Donnellan was prime serjeant and slightly senior in age, he was given the lower place, being appointed puisne baron in Hartstonge's room, while Doyne became chief baron, a place vacated by the promotion of Pyne to the chief seat in the King's Bench, and of Hely to the chief seat in the King's Bench, and of Hely to the chief seat in the Common Pleas. At the same time, whig malice inspired the removal of Cox and Jeffreyson from the privy council.
Chapter II Tories Triumphant Sovereign - Anne 1701-1714 a consequence of Cox's promotion, advancement came to Chief Baron Doyne and Baron Donnellan who found reason to change their political opinions, and a seat on the bench fell to an Irish barrister, Robert Johnson, whose devotion to the name of tory was fanatical....... Chief Baron of the Exchequer Nehemiah Donnellan, P.C. A year and a half before the close of Ormond's first viceroyalty a contest began between him and the English ministers as to filling a vacancy on the bench caused by the death of Chief Baron Donnellan.

LE10/3 - Baron Nehemiah Donelan's Will

[The document LE10/3 are actually notes made by Dermot when the family was being researched in about 1896. They consist of what is purported to be the Will, but from the notes looks to be more of a draft. I do have a certified copy of the codicil to the Will that is also notated hereinunder. In addition to the Will and codicil, the document also includes the notes by Dermot from the Deeds Office located at Henrietta Street].
