III. GERALD FITZ WALTER, or son of Walter, who was appointed by Henry I. to the Constableship of Pembroke Castle and other important offices. He married Nesta, daughter of Rhys ap Gruffyd, ap Tudor Mawr, Prince of South Wales, and had issue by her, three sons, the eldest of whom was IV. MAURICE FITZ GERALD, or son of Gerald. This, it will be noticed, was the first Fitzgerald of which we have any record, and he was the progenitor of the Irish Fitzgeralds. He accompanied Richard de Clare, Earl of Pembroke, popularly known as "Strongbow," to Ireland, and there highly distinguished himself, having, among other acts of renown, captured the city of Dublin. He died at Wexford in 1177. He married Alice or Alicia, daughter of Arnulph de Montgomery, fourth son of Roger de Montgomery, who led the centre of the Norman army at the battle of Hastings, and by her had issue - five sons, the eldest of whom was William, Baron of Naas, not Gerald as claimed by the supporters of the Colin Fitzgerald theory. Thus far the two genealogies may be said to agree, except in a few of the marriages. V. GERALD FITZ MAURICE, the second son, in 1205 became first Baron Offaly. The third son, Thomas, was progenitor of the original Earls of Desmond, who have long been extinct in the male line, the present Earldom, which is the Irish title of the Earl of Denbigh, having been created in 1622. Gerald Fitz Maurice married Katherine, daughter of Hamo de Valois, who was Lord Chief Justice of Ireland in 1197, and by her had a son, VI. MAURICE FITZ GERALD, second Baron Offaly, one of the Lord Justices of Ireland. Maurice died in 1257, having married Juliana, daughter of John de Cogan, who was Lord Justice of Ireland in 1247, and by her had three sons, Maurice, Gerald, and Thomas. Maurice Fitzgerald has no wife given him in the Colin Fitzgerald genealogy. Thomas, the youngest son, had a son John, who ultimately, on the death of Maurice, fifth Baron Offaly, without issue, succeeded as sixth Baron, and was, on the 14th May, 1316, created the first Earl of Kildare. Maurice Fitz Gerald was succeeded by his eldest son, VII. MAURICE FITZ MAURICE, as third Baron Offaly. He married Emelina, daughter of Sir Stephen de Longespee, a rich heiress, and by her had a son and two daughters. He was succeeded by his only son, VIII. GERALD FITZ MAURICE, 4th Baron Offaly, who died without issue in 1287, when he was succeeded by his cousin Maurice, only son of Gerald, second son of Maurice Fitzgerald, second Baron Offaly, as IX. MAURICE FITZGERALD, 5th Baron Offaly, who married Agnes de Valance, daughter of William Earl of Pembroke, without issue, when he was succeeded by his cousin John, son of Thomas, third son of Maurice Fitzgerald, second Baron Offaly, as
