It sounds like the Kirkness family you are researching could be related to mine.
My g.g.grandmother was Margaret Kirkness born Aug 1828, Orkney, Scotland. I am not sure when she immigrated to Canada but it was prior to 1862. She married David Harvey,
born Jan 4, 1828 in Edinburgh, Scotland. David & Margaret farmed in the Moncton area of Logan twp, Perth county, Ontario. Margaret died Mar 15, 1891 & David died on Jun 26, 1905. They are both buried in the Knox Presbyterian Cemetery in Mitchell, Ont.
I have just started researching in Scotland & would be interested to know if this is Peter's sister. Is this the
Peter Kirkness who was located in Huron twp?
