Michael Quin was elected Mayor of Limerick in 1848. In Griffith's Valuation he is recorded as holding the townland of Ballynisky in the parish of Clonagh, barony of Connello Lower, county Limerick. In January 1872 his estate at Lisnamuck, parish of Croagh, barony of Connello Lower and at Clonagh, amounting to 661 acres was advertised for sale by trustees under his will. He is described as "deceased". The sale rental records that he bought Ballyniskey in the Encumbered Estates' Court in November 1851 and Lisnamuck in February 1855. Lisnamuck was part of the Tuthill estate advertised for sale in 1854.
