We are researching a very important Parisian female artist that has been forgotten. Jeanne Louise Marguerite Donnadieu. Born 1864. She lived 4 doors away from Vincent and Theo van Gogh in 1886. Her address there was 17 Rue Laval (or Rue de Laval)which was changed to Rue Victor Massé in 1887. She was there at least from 1885 to 1897. We know she went to Pantin and was definitely there 1912 - 1914 at least. We finally found out that she had died in Lisieux, 1941, age 77. On the death certificate was a note saying she was divorced from someone called Houdard but no other information was available. Did she have children? Relatives? Friends. Where are her things? Writings? Other paintings? Only a very few are around but one of these is of Vincent van Gogh. She called it "The Misunderstood" rather than use his name so we have been asked to find some document that proves in writing that she knew him. He is on the canvas and they were close neighbours but for it to be accepted there has to be even more! Any help at all would be fantastic.
