|CLARA MANN PETERSON, 1910|
The 1900 Census records for Connecticut, show that there is a Clara M PETERSON living in New Britain, Connecticut (which is about 20 miles from Waterbury.) That record indicates that she is born February 1890, so if that is the same person, then she is nearly 21 years old in this photo, in 1910. I am not sure if that is the right person. The woman in this photograph looks younger that 21 to me. I would guess between 15 and 17.
The 1910 Census for Naugatuck, Connecticut (about 5 miles from downtown Waterbury) shows a 16 year old Clara P. MANN living with her parents Albert Mann and Sarah Mann, and her grandmother Maria Mann. Albert was 46 years old and working as a foreman at a woolen mill. This Clara Mann married Carl Edward Peterson in 1929. She died in 1964 and is buried in the Swedish cemetery in Portland, Middlesex county, Massachusetts.
