I believe I made a mistake about Marie being companion to the wife of the silk lampshade makers wife - that would be the wife of John's son, John James Victor (my grandfather). Berthe Larre was also French. Berthe was related to Rene Larre, director of finance for France. They are interred in same family plot in Oloron Ste. Marie France. I digress. I will be writing to Ealing library to see if there are records re buildings in Ealing/Acton area that John may have been contracted to do the civil engineering. I have to also determine if there would be records in England of architects and engineers and their certifications.
