Michael Obins died in 1798 and left a son, Michael Eyre Obins, to succeed him. In 1814, Eyre Obins took holy orders and sold the estate to the Sparrow family of Tandragee. George Montagu, 6th Duke of Manchester (known as Viscount Mandeville) married Millicent Sparrow in 1822 and came into possession of the estate. This family's legacy to the town includes street names such as Montagu Street, Millicent Crescent and Mandeville Street, as well as buildings such as the Fergus Hall (formerly the Duke's School and Church Street PS), and the Carlton Home (the Duke's former townhouse, latterly a maternity hospital/nurses accommodation and now private apartments).
