At www.cbgen.org I found a Sarah McGinnis baptized June 15 1861 at St Denis RC church, Barronsfield Road, Minudie Nova Scotia and she gives her full name as Sarah Louisa McGinnis and her parents names as James and Sarah Feltmate. Under comment it says "Acadia Iron Mines". The Feltmate people are usually Protestant which would account for her getting baptized at the time of or after her marriage to Mr. McGinnis. Unfortunately, despite my extensive Feltmate data base, I have not been able to find out who James and Sarah Feltmate are. The info above also has the note with it that the 1820-1848 vital records for the Minudie area are found in the registers of Memramcook Parish (New Brunswick).
