During the course of the 1594 John Neylon, son of then Bishop of Kildare Daniel Neylon (or O'Neylan as he is recorded in some documents), was bequeathed the castle of Dysert O'Dea near Corofin along with other lands in Inchiquin.  However, during the Cromwellian and Williamite wars of the 17th century a lot of Irish nobles lost their land and titles after the outcomes of these wars didn't go in their favour and English rule in Ireland took a firm grip. The Neylon family appeared to remain in the general area but no longer at the centre of political affairs.
