He was born in
Bree, County Wexford, to a prominent landowning family who are recorded in County Wexford from about 1250. He was the grandson of Sir Henry Keating,
knight. Little is known of his early life. He joined the Order of Knights Hospitallers, of which his family had been generous benefactors, rose rapidly through its ranks and in 1461 became Prior of the Order's Irish house at
Kilmainham, in succession to Sir Thomas Talbot, having taken the trouble of travelling to Rhodes in 1459 to canvass support for his appointment from his superiors. The motive for the attack is unknown, although crimes of violence, even among the ruling class, were not uncommon in that era. Twenty years earlier another Irish judge,
James Cornwalsh,
Chief Baron of the Irish Exchequer, had been murdered in the course of a private war over possession of a castle: his killers were later
pardoned for the crime. Likewise, when Patrick Segrave was murdered by Patrick White and others in 1455, all the killers were pardoned. Keating was not, it should be said, the first Prior of Kilmainham to have a reputation for lawlessness: Thomas FitzGerald (reputedly an illegitimate member of the great
FitzGerald dynasty), who was removed from office as Prior in 1447, was a notably turbulent and litigious individual, who clashed with
James Butler, 4th Earl of Ormonde and with Sir
William Welles, the
Lord Chancellor of Ireland, whom he was accused of
kidnapping. Prior
Richard de Wirkeley, in the previous century, was another violent and controversial character who headed the Kilmainham house. Keating was arrested and
arraigned for trial before the Irish Parliament on a number of charges, including
attempted murder, but the charges were dropped on condition that he pay Dowdall 100 marks in
damages (although it seems that he never did so). He probably owed his immunity from punishment to the influence of the powerful
Anglo-Irish magnate
Thomas FitzGerald, 7th Earl of Kildare, later
Lord Chancellor of Ireland, who acted as Keating's patron.
Prior of Kilmainham For the next few years, he seems to have run the Order House smoothly enough. He was later accused of
bankrupting it: in his defence, he pointed out that in 1467 his superiors in Rhodes had increased the annual payment due to the Order's central fund from the Kilmainham house from £40 to £70 without consulting him. At a Chapter meeting of the Order in
Rome, he pleaded without success for a reduction of the annual payment. He argued that the increase took no account of the Irish House's ability to pay, and insisted that he had been simply unable to find the extra money. The charge of
fraud made against him by later historians seems to be based on his general bad character, rather than on any specific crime. He succeeded in having some of the property alienated by his two predecessors restored. ==Politics==
