The OS six inch map 1st edition 1843 -1882 (viewable online though the National Library of Scotland) has a "Kinnonpark" located slightly North West of Tibbermore, but still within that parish I would think. It appears to be a substantial building with a few cottages behind. Given that the family are later located at Huntingtower, could it be that William was a labourer on this estate in 1847, which has been named as just Kinnon, or Cinnon later?
On a slightly different note, Huntingtower Castle is still there, and probably best known as the setting for the John Buchan Novel Huntingtower, whilst Tibbermore was the site of the Battle of Tippermuir when the Royalist forces of James Graham Marquis of Montrose defeated a covenanting army under lord Elcho in September 1644.
