X. JOHN FITZ THOMAS FITZ GERALD, sixth Baron Offaly, and first Earl of Kildare. From him, by his wife Blanche, daughter of John Roche, Baron of Fermoy, are descended the present Duke of Leinster and other Irish Fitzgeralds. He died on the 10th November, 1316. Several important particulars bearing on the points in dispute are noticeable in this genuine Fitzgerald genealogy, a few of which may be remarked upon. (1) There is no trace of a Colin Fitzgerald, or of any other Colin, in the real family genealogy from beginning to end, down to the present day. (2) Gerald, the 4th Baron Offaly, died in 1287. He was succeeded by his cousin Maurice, as 5th Baron, who in turn was succeeded by his cousin John Fitz Thomas Fitz Gerald, who died comparatively young in 1316. According to the Colin Fitzgerald theory, this John, first Earl of Kildare, was twice married, and by his second wife had six sons, of whom Colin Fitzgerald, who really ought to have been described as Colin Fitz John - for it will be observed that the Chiefs in the real genealogy are invariably described as Fitz or son of their fathers - was the eldest. This was impossible. How could John Fitz Thomas Fitzgerald, who died at a comparatively early age in 1316, have had a son by his second marriage, who must have arrived at a mature age before he "was driven" from Ireland to Scotland in 1261, and be able to fight, as alleged by his supporters, with great distinction, as a warrior who had already an established reputation, at the battle of Largs, in 1263? Let us suppose that Colin's reputed father was 70 years old when he died. He (the father) must thus have been born as early as 1246. Let us take it that his eldest son, the reputed Colin, by his second wife, was born when his father was only 24 years of age - say in 1270 - and the result of the Fitzgerald origin theory would be that Colin must have fought at the battle of Largs 7 years before, according to the laws of nature, he could have been born. In other words, he was not born, if born at all, for seven years after the battle of Largs, four years after the reputed charter of 1266, and 40 years subsequent to 1230, the last year in which either of the witnesses whose names are upon the alleged charter itself was in life. (3) But take the genealogy as given by the upholders of the Colin Fitzgerald origin themselves Maurice, who died in 1257, had, according to it, two sons - Thomas and Gerald. This Thomas, they say, succeeded his father as third Lord Offaly, and had a son, John, who, by his second wife, had Colin Fitzgerald. That is, Maurice, who died in 1257, had a great grandson Colin, who, as a warrior of mature years and experience, fought at the battle of Largs only six years after his great-grandfathers death. But there was in fact no Earl of Kildare at this early date. That title was, as already stated, not created until 1316, twenty-eight years after his son Colin Fitzgerald was, according to the testimony
