The matted photograph, taken by the studio of Tuttle & Son of Belfast, Maine, measures about 7" by 5-1/4". The photograph itself measures about 4-1/2" by 3-1/2".
From brief online research, hopefully correct - corrections and additions requested:
Gertrude Mae Johnson was born October 14, 1883 at Bucksport, Maine, the daughter of Amos A. Johnson and Bertha E. (Crockett) Johnson. After graduation Gertrude taught school. I believe she married twice:
- November 29, 1906 at Bucksport, Maine: teacher Albert White Austin, son of Elmer B. Austin and Emma Frances (White) Austin of Buckfield, Maine. Gertrude and Albert divorced.
- March 1, 1910 at Portsmouth, New Hampshire: Portland, Maine physician Walter Herbert Witham, son of George W. Witham and Mary E. (Cushing) Witham. Dr. Witham was divorced from his first wife, Eva Mae (Tuttle) Witham. Dr. Witham was born on Long Island, near Portland, Maine, and died there in 1930.
Note that the text on the linked site for Gertrude has her birth year as 1884; fortunately, the text is accompanied by a photograph of the stone which bears the correct birth year of 1883.
