Hi I am researching the Pictou County Coady line.
I i have a Frederick Michael Coady (b.25 Feb 1894) married Mary Eleanor Delorey.
Fred's Father Joseph Cottie (b. 17 Aug 1862 and located on an 1881 census as Coté) married Margaret Walsh (b. 1872)
Joseph's father Imable Cottie (b. 1818 possibly I. Mable) married Catherine Long from Nfld & Labrador
Children of Joseph Cottie and Margaret Walsh:
John Simon Coady b. 4 Jan 1888
Claire Cottie b. 1890
James Cottie b. 1 Mar 1890 in Goshen, Nova Scotia
Joseph Coady b. 4 Feb 1892
Frederick Michael Coady
Annie S Cottie b. 16 Mar 1896
Henry Francis Coady b. 8 Apr 1897
Clara W Cottie b. 10 Apr 1900 (baptized Clara Mabel Coté 25 May 1900. St. Patrick's, Lochaber, Antigonish)
Mary Agnes Cottie b. Aug 1902
William A Coady b. 15 Nov 1906
At some point Cody and Cotie also came into the mix of surnames.
I have researched the Margaree/Sheet Harbour Coady's and do not believe there is any connection at all. These Coady's arrived from Ireland, and I believe Imable Coté was a Seaman who possibly came from Quebec. I have always told that we had a connection to Buffalo Bill (his grandfather was born in Ontario and great grandfather was born in Massachusetts so I guess it's possible..)
