I'm not sure if this is any use as I'm just starting out. My great great grandmother was Elizabeth Murray Duncan Cheyne (1879-1953) and her husband was Alexander Cheyne (1878-1946). I know that a lot of my family emigrated to Canada in the early 1900s and later on as well, where I'm not sure. If you remember any family visiting you may remember my great great aunt Barbara Murray Duncan Milne who went over quite a few times up until the 1970s. I've got a bit more information if you need it anyway.
