Anne O'Hare McCormick sisters

Family photo, taken around 1890 since youngest sister Florence appears to be about 4, and she was born in 1886. The back was labeled much later with their married names: 1-Mabel Gill, 2-Florence McCalley, 3-Anne McCormick.
The unpublished photo was taken in 1890 or earlier. No copyright notice or name of the photographer is shown with it. The general rule for anonymous unpublished work in the US is it becomes public domain 120 years after the photo was taken, so in 2010.[1]
More specifically if it was taken by a parent, they died in 1923 (father) and 1931 (mother), so more than 70 years have passed since the death, and the same source says it has entered the public domain. [2]
