Ngatiira Tangihia Savage

Ngatiira is my great great grandmother. I come from the line of her son, Benjamin Savage II. Although I have a little information about her genealogy-wise, I don't know an awful lot about her life or what she looked like. I would dearly love to have a photograph or information about where I might be able to see one. If not a photo, then any other information about her.
Many thanks,
Julie.
