Recommended books or articles on the Acadians?
I've got a good bit of Acadian heritage, but sadly my knowledge of my ancestors is rather limited. All I know about the Acadians has come from my (Acadian) grandparents and some Wikipedia reading. Can anyone point me towards a book that covers the general history of the Acadians and our expulsion? Thanks.
