The struggles within the O'Neill family are well known. The Earl Hugh suppressed his own cousins more than he did the English in the first few years of his reign. In 1583 and 1587, the Earl put down any other claimants to the Chiefship, including Tirlough O'Neill, until he had himself recognised as Sir Tirlough Linneach's heir as The O'Neill Mor. In 1590, the Earl hung Hugh "Gaveloch", son of
Shane O'Neill for conspiring against him. In 1593 the Earl had his cousin Phelim McTurlough, Lord of Loughinshollin and chief of a sept within the Clanaboy O'Neill, murdered on Toome on the Bann River, and instilled himself as the Lord of Loughinshollin. Hugh and his McShanes were able to weather the rise of the Earl and had split loyalties to the Earl when fighting the English. However, with the loss of the Nine Years' War in 1603, Hugh McShane was able to edge out the Earl and became the new Lord of Killetragh and controlling most of the Lordship of Loughinshollin. He maintained independence from 1600 to 1606, and then replaced the Earl as the sole lord in the years following the Earl fleeing from Ireland in 1607. However, with the
Flight of the Earls and the power vacuum that created, Hugh McShane and the other smaller lords had to deal with the sudden presence of the English military in Ulster. For a while, Hugh benefited from this independence. Sir
Arthur Chichester put out a warrant for wanted rebels and in 1608 Hugh McShane, his brother Phelim, and Hugh's wild McShanes captured Shane Carragh O'Cahan in Glenconkeyn forest. They turned him over to Chichester for a pardon and remit of some leases for two years. In 1610 Hugh McShane was on the jury that divided the lands out of the forfeited estate of his cousin the Earl of Tyrone. In doing so Hugh received of the Earl's lands around Dungannon, and in 1611 another in Tyrone. Conn MacShane held an adjoining portion, and he and Henry both received large estates in Armagh and Fermanagh. Hugh's new neighbour and friend was the departed Earl's nephew Brian Crossagh, son of Sir
Cormac MacBaron O'Neill, something that would cement a friendship impacting them both in later life. ==Later life==
