The back side of this photo is marked 1892 by the photography studio, which probably indicates the year it was taken, for the photographer’s files. It was taken in Trieste, Italy, according to the photographer’s information.
From left to right, I believe these folks are:
Lisette (seated, with flowers in her lap), Louis (sitting on the decorative railing behind her), their father Auguste/Augusto (standing nonchalantly next to Louis), their mother Laure, baby Victor (toddler in a dress), and Laure’s father, Victor Chartrey. This photo was taken a few months after Laure sent her father a photo of herself and the baby, along with a letter explaining their difficult financial circumstances.
Auguste Margutti was a trained accountant, a former employee of the Suez Canal company. I believe he was first employed to help manage finances for the work crews building the canal. Then he managed the office at the Suez end of the canal, until the Suez Canal company was re-organized, after the Anglo-Egyptian war. Auguste finally took his young family to his hometown of Trieste, but as a simple accountant he had difficulty providing for them. According to old letters I have found, it appears that Auguste disappeared soon after this photograph was taken. Many years later, the man who would become Laure’s second husband, Mr. Gautier, hired a private detective to find what had become of Auguste.
Auguste would be the uncle of Albert Margutti, brother of Henri, son of Alexandre. Auguste died in a Catholic Charity hospital in Punta Arenas, Chile, in 1917.
