What on EARTH does this say? Place name in Scotland

[TressiliansStone]

I'm enjoying the National Archives' free access at the moment, but some of the handwriting is turning my eyeballs inside out!

Hillend I can make out, but what on earth comes next? All I can decipher is that they are in Roberton and Wiston parish in Lanark.

I've moved on from my original query, but just come back to say I rest my case about the limitations of legal hand.

Imagine having a legal case resting on this will!
"And where are the lands in question?"
"We're not sure m'lud. Perhaps the plaintiff would like to suggest a few names, and we'll see if they look likely..."

Fortunately this isn't one I need to know.
