[2] Timothy Pont described the property in the early 17th century as "A pretty extensive range of land, now divided into several farms bearing the names of "Blacklaw", one of which is distinguished as Blacklaw-hill.

"[1] A prominent feature is described as "On the farm called Blacklaw-hill is a mount, or small hill, of a conical shape, covered with a beautiful verdure, at the base of which are to be found some fine old trees, indicating the site of a Mansion in former times.

The site was once surrounded by a drystone dyke, possibly recycling stone from an old building, to exclude grazing animals and a few old beech trees remain.

The 'I' stands for Iohannes which is now written as 'John' and the surname indicated the Brown family, originally of Gabrochhill where they had resided for many generations.

The datestone is not located as a keystone on the arch of the bridge and therefore could have been inserted at any time, in addition, as stated, it is made of red sandstone.

[9] The 10 merk land of Blacklaw and Blacklawhill passed into the hands of the Cunninghames of Corshill and on 23 September 1687 Sir Alexander Cuninghame and his mother, Lady Corshill, Dame Mary Stewart, granted a charter of the 2.5 merk land of Blacklawhill to John Brown in Gabrochill (sic).

[7] In 1747 Jean, only daughter of John Brown of Blacklawhill married William Mackie of Fulwood and Easter-house of Corshill.

[12] In May 1685 the tenants of the lairdship beneath the Black Law were pursued by the Barony Court for "cutting of young root grown trees within the parkes of Corshill"[5] In December 1701 John Brown and Robert Faullis of Blacklaw were requested by the Barony Court judge to assess how many swine could be grazed on the common pasturage of Hareshaw and Corshouse.

[14] The Ayrshire Ordnance Survey name book of 1855 to 1857 records Midtown of Blacklaw as a" farmhouse with outbuildings garden etc.

"[15] This was a very large and valuable area of common grazing immediately to the south of Blacklaw, then known as Machirnock or Maucharnock,[16] now known as Glenouther Moor.

and a royal letter of 1534 states that the Cunninghams had not been invested in the moor and it was decided that the souming was split between Polkelly and Rowallan.

[18] In 1594 William Mure of Rowallan complained of the excess of Polkelly's grazing cattle and geese on the moor, despite having obtained a caution of lawburrows on May 20, 1593.
