Try http://www.lawsons.ca/ and search burial index there is a record of an Ann and an Alma McCann in 1870 No sign of John on the island but 1881 census shows a John married to an Mary Ann with a daughter Anne Jane 13 at Preston. The coincidence is that John -Isle of Man- had a sister with the same name.
The son John Philip was boarding at this time with James and Jane Kennish in Maughold. James was a printer.
