Hi SFA,
I'm not related to the Andersons that I know of but came across your posts tonight when I decided to google Alex Anderson, Pittentaggart, Tarland. This is the name I found on a tooled metal cigarette case that I bought from a garage sale in Alberta, Canada about 10 years ago. The date on it is 23rd Mar, 1914.
I Wonder if you (or anyone else) know if any of the Alex Andersons from your family came to Canada and perhaps owned this case?
