Just to add my twopennyworth - I too, am related to the Mckenzie's from Rherivach / Scoraig.
My friend and I have visited there twice.
My ancestral family home is now known as Shanti Griha.
A sister of my great-grandmother is buried in Bord Buie cemetery, Dundonnell, but I haven't been fortunate enough to find out where any of the others are buried.
As a footnote, CISSIE88 turns out to be my 3rd cousin - perhaps Mavey and I are related in some way too.
It's all sooooooooooo exciting.
