Col. Tasker was a "Chancellor of Ireland and a man much renowned for wealth and honour." "He died after the "Derry Spree." Col. Tasker had just two daughters, the eldest Barbara, married Captain John Keyes, who was an officer under Col. Tasker. "Magdalen, the younger, was married to Colonel Porter. He died some time before the 'Derry Spree.' Then "she ran off with one Polk, who was a companion or friend to Colonel Porter. The Porters were a strong connection in this country at that time. It appears that the Porters threatened Polk, and she having no family to Col. Porter, his family obtained most of the property in the estate of Moneen."
Col. Tasker's seat was "Castle Hill," near the village of Ballindrate, commanding a view of the river Dale. It would appear that the Lieut. Roger Tasker above eventually was promoted to be a colonel and acquired more estates in the same general area as his "Cavanacor."
Barbara Keyes, wife of Capt. John Keys, "Castle Hill," (which had been the Colonel's seat), and his youngest daughter received "Moneen," described as "lying in the parish of Lifford, near Strabane, on the river Foyle, consisted of six hundred acres."
