Hello, and thanks in advance for any answers/sources you might provide!

My question is driven primarily by geneology, although that is not directly what I am asking about. To dive right in:

I have a family story that I can't verify, and I'd like to know what you think about the probability that it is either true, or has a kernel of truth. The story is that my great aunt, my paternal grandmother's oldest sister, was born and (in her early years) lived in a wigwam in Dixmont, ME. My paternal grandmother was the youngest of 16, and born in 1919. She was the last (by a wide margin) of her siblings to pass away, this occurring in 2001. She is the one who always told me this story when I was young. To complicate matters, very few of her older siblings had children, and they were mostly only children. My youngest relative (aside from my father) is twenty years older than my father is. My father was an only child as well. Needless to say, there is no family network to speak of, and what few relatives I've been able to find and contact either don't have any information, or just don't really care.

What I'm asking is - is it possible this family story is true? If so, is there any legitimate way I could go about researching it? Dixmont Maine in the 1800's was apparently right on the stage road between Augusta (the capitol) and Bangor, a major location for lumber processing/shipping, but the "town" itself still never amounted to much, so I'm unsure what records might be available, and my initial assumption (please let me know if I am off base) is that they wouldn't much care about tribal matters regardless. It's possible I might find something about my great grandfather, who was european of primarily English descent, but that would be it.

Second - Can someone point me to some high quality books or papers on the Penobscot tribe specifically?

Again, thank you very much for any input you have!
