Can anyone find Norman Nicholson/Nicolson - b: abt.1820, living in the parish of Snizort, on the Isle of Skye? In 1850 he married Ann Cameron in Snizort. No idea of parents or siblings. He may not be on the 1851 Census because he emmigrated to Canada sometime around 1851.
Your search would be easier if you had his parents names. Perhaps his Canadian death cert. would list them? Did he emigrate on his own? Perhaps siblings emigrated with him.
