I'm searching for the mother of Dominick Irwin born before 1840. His father was Edward Irwin, gentleman, as on Dominick's marriage to Jane Patterson of Cunicahill on 9th April 1868, in the Church of Ireland Church at Rahiney, Granard, Co. Longford. Jane Patterson's father was James Patterson, farmer (again no mother listed on the parish marriage record).
Is there anyone who can help me? I do not have easy access to Church of Ireland records as I live in New Zealand.
