The Coadys that Shirley is writing about is a completely different group of Coadys from Margaree. Our family group may have initially been Catholic, but quickly became Baptists, although still settled in Margaree, until James moved to Mainethrough New Brunswick.
At least two histories of the area (J.L.MacDougall's History of Inverness County Nova Scotia" (accessible online) and John Hart's "History of North East Margaree" note the three Coady families.
Our ancestors in that Baptist group of Coadysare John, the father of James, who was married to Ellen Shanahan, and Patrick, the father of John, who was married to Mary Maria Ingraham of Margaree. Patrick came to Nova Scotia through Newfoundland during the Rebellion of 1798 in Ireland, and was from Kilbride, Callan, Kilkenny, b. ca. 1785. His father was James C. Coady and mother Brigit Leighlin, according to my best sources thus far.
James, Harriet, and their children became Methodists after moving to Maine, perhaps when the rest of the BaptistChurch there did.
