Hi David,
Thank you. Here's what I have from my notes. The square brackets are mine.
In the parish register of Keir, in Nithsdale, Dumfries-shire, in 1810, "29 March a son of John Hamilton & Anna Scott in Winsover [Windsover] named John". The land of Windsover or Windsowr Hill, near Auldgirth, comprising about 60 acres, was in the Blackwood estate of William Copland, Esq. of Colliston.
