Hi, mcadamsd,
The word following "Charles Clarke" is the name of the farm he lived on, same with the word following the second witness. Here is my intrepretation:
Charles Clarke Urlurhust & Ewan M'Ewen Scottack
Scottack appears to still be in existence but you will need an ordnance survey map of the early 1800s to attempt to locate the homestead of Charles Clarke.
I hope this helps.
