I'm searching for a Murdock/Murdoch, in the family tree of my son's mother. The name is Elizabeth Sarah Jane Murdock, married to a Robert McKay, about 1860 to 1900. I have them as parents to Margaret B. McKay, born Jan. 11, 1883, in Tatamagouche, Nova Scotia(near Pictou). This same Margaret later married Daniel Ray Keith, ca 1901 near Havelock/Butternut Ridge, New Brunswick. Any help provided would be welcome.
