There may have been a castle on the lands of Aberlednock although its exact position is no longer clear.
Pont’s late 16th century map of Strathearn shows a large castle to the east of a river or burn to the east of Comrie. To the west of the same burn is a building named Ton-beiran. Spanning several buildings in this area is the name Abyr-Lednaigs or AbyrLednaigs which may be in reference to the division of Aberlednock into Wester Aberlednock and Easter Aberlednock. Today the site of Ton-beiran is occupied by the house of Tomperran, to the west of the Milton Burn. The croft of Thomperroune or Tomperran is mentioned in the 15th century in association with the lands of Westeraberlednok or Wester Aberlednock.
Aberlednock was one of the five constituent parts of the old estate of Monzievaird along with Fordie, Clathick, Ochtertyre and Monzievaird itself. Aberlednock, meaning confluence of the River Lednock, presumably stretched to where the River Lednock flows into the River Earn and Coney Hill motte may have been the early seat. Later the main residence of the estate may have moved to the east of the Milton Burn.
I have placed the site of the possible castle at the 19th century house of Knowehead, which occupies a good defensive position on a small hillock immediately to the east of the Milton Burn, pending further research.
