Thanks Kay for taking the time and trouble to transcribe all that!
It all ties in with the IGI couple William Clague and Margaret Brew married 28 Jun 1835 Braddan who appear with the correct children in censuses from 1851 -1871 at Ballachurry, with widow Margaret and Craine granddaughters at the same place in 1881. Only the daughter Jane b.1842 is missing from the Will - she could possibly have married William Kissack (IGI 12 Jul 1866 Santon) and had the daughter Elizabeth mentioned (IGI c.2 Jun 1867 Santon) although I can't find the mother in 1871 or Brian's burial index.
Ideally I'd like to make a connection between this William and the Robert Clague who died 1849, so if anyone's got that will tucked away somewhere I'd love to see it!
Thanks once again.
