I uploaded the 1954 yearbook for Columbia School in Rochester. This was a private girl’s school. They merged with Allendale (boys) School in 1971.
There were only 16 seniors in 1954. There are nice large pictures of each of the young ladies along with a circular candid photo. Then there is a page that has a small baby picture of each.
The yearbook has pictures of school activities including a dress committee and a social welfare committee (in the picture). No pictures of any sports but I know they had sports as there is a picture of the athletic association.
The are pictures of every class and all the students at least have surnames. The nursery school class and Kindergarten have some boys in them.
