I have a Christina Cameron who married Lachlan McPhee in Ardnamurchan. My ggg-grandfather Donald McPhee is one of four children of Lachlan and Christina. He was born in 1834. I am unable to find any record of christina's birth or death. Or Lachlans for that matter. Perhaps you could keep me in mind if you manage to stumble across their names. As I'll do the same for you!
