Hi,
I've been hunting for Blacklaw(s) and found a reference to a Blacklaw in Fifeshire with no information but there's another west of Glasgow, near Paisley. Found the last one in an old reference book in the National Library of Scotland "up the river on the north syd 1m. above Swynstie is Blacklaw, a great hill, the springs not far far it. Southeast frae Blacklaw 1m is Carnehill at the head of the river Anok whilk river cums out of the black loch". I also checked out old parish names but nothing came up for Blacklaw(s). It could be an estate. Good luck with your further hunting.
