My 3x great grandparents, James and Ann Tuttle, adopted a girl sometime between 1850-1855. She appears in their household on the 1855 Massachusetts State Census, and it is specifically noted that she is adopted. In 1855, she was approximately 12 years of age, and her name was given as Harriet. She does not appear in the 1860 Census, when she would have been approximately 17. The 1855 census also states she was born in MA. I would dearly love to learn more about my aunt Harriet. Can someone help point me in a direction to uncover birth information, death information and marriage? Thank you!
