It looks like William was baptised at Kennoway s of Thomas Thomson and Elizabeth nee White 11.1.1856
By 1901 Thomas his father had died (death 26.1.1892 and Will 1894) and they are at Heathewinch Farm House Knnoway
Elizabeth 76 born Morniemal Fife
William 45 farmer K
Catherine 38
Thomas 35
Robert 15
They are in the household of Andrew Mill 54 railway signalman and his wife Jessie on the entry I spotted but they seem to be neighbours rather than living in same house.
Will see what else I can find
This is it mentioned on the OS 1855
