Gabriel Porterfield and his wife Jean Maxwell had a conjunct liferent of 'Halketh' and its loch on a charter of Robert Montgomerie of Hessilhead, dated 24 May 1634.

[3] Blaeu's map of 1654, based on Timothy Pont's work of the late 16th century, shows a 'Halkhead Loch', with a single property, Halkhead, nearby.

Paterson records that the cost of the loch drainage was shared between the surrounding proprietors and the creation of an excellent meadow was the outcome.

Many drainage schemes also date to the end of World War I when many soldiers returned en masse to civilian life.

One stone on the summit has a vertical hole drilled to the depth of four feet or so, presumably to be used for 'slot' for a flagpole for flying a standard, a similar arrangement to that which existed at the Borestone at Greenhills near Beith.

[10] This surname Halket was derived from the lands of Halkhead, Renfrewshire, although a family bearing the name de Ross have long been in record as possessors of the property.
