Stonebyres was an estate and country house in Lanarkshire, Scotland, belonging to the Weir, or de Vere, family from earliest recorded history.
Stonebyres Castle stood by the Linn Burn, a tributary of the River Clyde, around 4 kilometres (2.5 mi) west of Lanark.
[6] Stonebyres was then leased out for the remainder of the century as James's only surviving daughter Amelia, having married Sir William Monteath Scott of Ancrum made that her home.
[6] Dame Amelia's daughter, Constance acquired the estate from her mother and in turn sold it to James Noble Graham, of Carfin, in 1906.
[6] Constance died in 1933, and the house passed to the Department of Agriculture which created small holdings for unemployed men from Auchenheath.
