Once she was settled in Rome, Catherine's distress did not subside. She found the Italian climate, the separation from her children, and her diminished lifestyle all unacceptable. Catherine asked to return to Leuven to reunite with her children, but her petitions were constantly denied by Spanish authorities. It seems her husband also refused to let her relocate to Leuven. When Catherine pleaded for her health, frequently complaining about the "city's air", the authorities suggested she go to
Naples or
Sicily. A doctor who arrived in Rome to attend to her ailing husband confirmed that Catherine was sick. He treated her and she showed marked improvement. It has been suggested that in
Rome she had an affair with Robert Lombard, the nephew of
Peter Lombard, the Catholic
Archbishop of Armagh, who was a noted supporter of the Earl. Robert Lombard was a spy for the Crown and may have attempted to get information from the Countess about her husband, which he relayed on to
London and Dublin. The proposed timing of the "affair" coincides with Peter Lombard moving out of the residence he shared with the Earl for seven years. Hugh O'Neill died on 20 July 1616, Catherine's step-sons
Hugh and
Henry died from illness in 1609 and 1610 respectively. These deaths only intensified her increasing isolation. Furthermore, she became estranged from her oldest son Shane over her late husband's will. According to the will, she would receive 172 crowns per month - short of her Spanish pension of 550 crowns per month. The remaining 378 crowns per month would be split amongst O'Neill's dependents. However, if Catherine failed to maintained "herself honorably,... not a penny is to be given to her." The unhappy retainers asked the late earl's secretary, Henry O'Hagan, to inform Shane that his mother was refusing to give them the money bequeathed to them. The claimants asked for Shane's support and even suggested that Catherine be "enclosed in a convent of nuns". They cautioned Shane to send someone to Rome, to deposit his late father's money and valuable in a bank before Catherine could. Historian Jerrold Casway believes this saga exposes the Irish refugees' "extreme dependency", as well as Catherine's estrangement from her husband and his retainers. Shane and Catherine disputed over her share of the Earl's pension as well as the maintenance of his dependents. The late Earl's trusted friend and former Spanish ambassador to Rome, Count de Castro, asked
Philip III of Spain for compassion towards Catherine's "miserable state, alone and without property in a foreign land... with no other protection than that of Your Majesty." He requested funds to allow Catherine to "travel proportionate to her quality and to the manner in which she must be escorted". After much debate, Phillip concurred. In September 1616, he directed Castro's successor, Cardinal
Borja y Velasco, to grant Catherine the same allowance as her late husband, to the frustration of O'Neill's dependents. Despite the royal grant, Catherine failed to receive any compensation, and without this the dependents also suffered. Throughout 1617 she unsuccessfully petitioned for her monthly stipend. She eventually escaped to Naples to evade creditors, to alleviate her poor health and to be closer to her new benefactor
Pedro Téllez-Girón, 3rd Duke of Osuna. On 22 June 1618, Catherine described herself to Philip III as "this afflicted and unprotected widow," who feared "less to die of hunger than to become the ridicule of the English." In response, Philip ordered a prompt payment to her. == Death and legacy ==
