Our Lady of Peace parish is at 522 Carroll Street, Brooklyn NY 11215-1030, telephone 718-624-5122, west of Fourth Avenue and near the Union St. station of the R train. It seems that the Immaculate Conception Province of Franciscans, O.F.M., serve the parish.
The parish school is now occupied by PS 372, The Children's School. Note the two flags, two crosses.
If you have not done so yet, you may want to view the Comments link above the first photo. One inquiry is for photos from the 1930's. Google's Blogger or Blogpost hides the email addresses on most profiles, so communication can be difficult. For photo searches, I suggest trying the Image search on Google, Bing, or Flickr. The Brooklyn Public Library has a rather good (but not all-inclusive) photo catalog search tool linked here.
