MUNRO, BRUCE, Wick Cai, 1831

I am seeking any information on the paternal ancestry of James Munro, born Wick about 1831. His mother was Janet Bruce, born Bower in 1807 to Alexander Bruce and Margaret Stephen (also Steven and Stiven). I've found the family, with Janet Bruce as the head, in Wick in the censuses of 1841 and 1851. According to the census, James also had a sister, Janet Grant, b about 1836. James was a shoemaker, later removing to Thurso. Thanks in advance for any information.
