Anna Mae Aquash was a Micmac from the Shubie Res.
My recollection is sketchy but here are a few possible sources for
Micmac history:
L.F.S. Upton, Micmac and Colonists which is an excellent history of
English-Micmac relations from 1713-1867 but has a pretty good general
description of life before and after as well.
Christien LeClercq was a missionary to the Micmac and wrote a book called New
Relations of Gaspesia. I think it is from the late 1600's but was published
by an historical society in around 1910.
The Jesuit Relations, maybe volumes 1 and 3?, seemed to have recollections of
the Micmac from Pierre Biard.
Silas Rand was a missionary to the Micmac in the late 1800's and published
some books of their legends. Micmac people were largely hostile to him.
For more recent information I don't really know much. A sociologist named
Jeanne Guillemin (spelling?) published a book called Urban Renegades about
Urban Micmac in the late 1960's.
I know that a few years ago the Maine Micmac band received federal
recognition and quite a bit of money as a result.
Perhaps the best source for trying to trace relatives is Ruth Holmes
Whitehead's The Old Man Told Us which has excerpts from primary sources over
the past five hundred years. It was published a few years ago. She tries to
trace names and permutations throughout the text.
I hope this was of some help.
