The Cruel Gillanders refers to James Falconer Gillanders of Highfield, a factor who evicetd many families from the estates of Rosskeen, Kindeace, Strathconan, all I believe in Inverness -shire, although I could be wrong. Can't help with the other refs, I'm afraid. Try reading "The Highland Clearances" by John Prebble, although this book is not without its critics
