Early 1900s photograph of Margaret Esther Keyes at the age of two years and two months, as noted on the reverse.
The photograph was taken by the Heath studio of Bangor, Maine.
I didn't find a Margaret Esther Keyes in the Bangor, Maine, area; perhaps she and her parents were visiting. I did find a Margaret E. Kyer at Brewer, Maine, across the Penobscot River from Bangor. Margaret's parents were Eugene James Kyer (Kiah) and Maude E. (Muldoon) Kyer.
If you have a theory as to Margaret's identity, please leave a comment or contact me directly.
