Patrick Melvin writes of a grant in 1720 of the castle and lands of Lydacan by Protestant trustees to Patrick Lynch. Soon afterwards the estate of approximately 1,000 acres was mortgaged to Edward Eyre of Galway. By the early 19th century the estate was in the hands of the Court of Chancery and some members of the family had emigrated to Argentina. Patrick and James Lynch, merchants of Lynch's Castle, Galway, bought the estate from the Court. The Lynch brothers had also bought the estate of the Frenches at Moycullen. Both properties passed to Andrew Henry Lynch, the son of Patrick. At the time of Griffith's Valuation the representatives of Andrew H. Lynch were leasing the property at Lydacan, in the parish of Claregalway, to Peter McDonald.
