Good luck with your search . I have GGGF named Alexander McPherson/MacPherson , also born in 1816 in Scotland who came to Canada before the 1841 Census so he is not found on it in Scotland . I knew he came from the Isle of Skye but since they used the Highland naming tradition , I found it impossible to track him back into Scotland . If your family used the same names over and over again then this naming readition might help . They would have named their first son , after Alexander's fatherand the second daughter after his mother .
