You are not in my branch of Caodys, so I am not a direct relative, but I may have a lead for you from J.L. MacDougall's History of Inverness County County, Nova Scotia, under "South West Margaree", p.413:
"James Coady, a fourth brother [to Martin, Peter, and John Coady] immigrated first[from Tipperary, IRELAND], to Mirimachi and moved to Margaree somewhere about 1840. He was married to Margaret Butler. Their family consisted of John, Michael, Peter, William, James, Patrick, MArtin, Ellen, MAry, and Margaret.
[The children] James, Patrick, and Margaret (Mrs. Murphy)moved to Sheet Harbor, Mary, Peter, and Martin died young. Ellen married Malcolm McDonald who later settled near Margaree Harbor. John married Helen Hylan, Michael to Mary McDaniel and William to Jane Dunn; the last named moved some years ago to a farm at Little Bra D'Or. "
I hope that this information will assist you. Perhaps James Coady's son James married Cather ine Faulkner, or perhaps a son of that James or of Patrick is the James you seek.
