Dear Darryl, Yes, your folk are not my folk. From my records are the following: My John McDonald of Mariposa Township married Christy McPherson in Eldon Twp, Victoria County on 24.4.1850. His sister Christy married Alexander McDonald in Mariposa Twp, Victoria County on 26.3.1850. Do you know the parents of Christy or is that what you are trying to determine? How do you know she, though in Grey County, has a connection with Victoria County? Was your Christy born in Canada or Scotland, says the 1861 census? All the best. Elizabeth.
