Your welcome. Probably no surprise about not finding records of the Giuseppe Calcagni from our family in Algeria. He worked in construction/engineering and had previously worked on the construction of the Suez Canal. In Algeria he was working on the construction of a railroad. The family story is that he while working in the middle of the desert and was buried on the spot. All other family members were back in Bisuschio.
As I mentioned the two sons eventually settled in Chile. One daughter, Angela, went to Massachusetts, USA. She maried a Catella, also from Bisuschio. The other daughter, Disolina, stayed in Bisuschio and married Angelo Rossi.
