So sorry to her this sad news.
This is the only picture I could find of Marlin, from 1938 (he was 5, I think).
He's the boy wearing suspenders in the front row, with Olga's right hand on his shoulder.
From left to right:
Front row: Fred Freud (Theresa's brother) holding Bobby on his lap, Marlin, Ernest, Audrey (with a ball), and Ron
Middle row: Neni, Olga, Pauline, Yolan
Back row: Ray, Joe, Theresa, Isidor Somogyi, Basci (Neni's husband), Ralph Fisher (Yolan's husband) and Henry Hagadus
