As suggested by Anne Lifshitz-Krams, Isidore DONN died indeed at
Villefranche sur Mer on January 27, 1898. The corresponding act can be
found on line (page 305) on the Website of the Departmental Archives of
Alpes Maritimes. Age 35, painter, married, born at Vilna (then Russia)
from English parents. He lived at Nice but died at the Villefranche surMer Hospital.
In the library of our Society (Cercle de Genealogie Juive), 45 rue La
Bruyère, 75009 Paris, we have a list of the graves of the "Cimetière du
Château" at Nice, where he might be buried. But, unfortunately, I am
not at Paris at present and the library will be closed during the whole
month of August. Be patient !
