Located in Canada: Johanna de Haas who was also known as Zwarte Jopie. Johanna’s full name was Johanna “Jopie” Atalia Gersina de Haas.
Dutch police spoke at a conference with Canadian colleagues about Johanna. The Canadians found her in the Vancouver Island registers as passed away naturally September 12, 2010, at the age of 74.
Apparently, Johanna de Haas married several times. The first husband is still alive, the second passed away. It appears Johanna just left the Netherlands and kept quiet all this time.
Johanna “Jopie” Atalia Gersina de Haas was last seen on February 8, 1960, Amsterdam, the Netherlands. In 1957, she gave birth to a baby girl who she called Roos (in English: Rose). Approximately six weeks after the birth, she gave her daughter up for “adoption.”
According to the magazine the WeesperNieuws, this adoption took place in a café on the Amsterdam Zeedijk. Jopie remained in the red-light district for a few more years. According to the magazine, she left for Hemer, Germany in February 1960 accompanied by a German soldier. Not one source I looked at can back this up with materials, links, or data.
There was speculation that from Germany, Jopie travelled to Canada or to the USA. According to some websites there were sightings of her in Quebec, Canada and in the USA.
The Algemeen Dagblad newspaper article is here. The authorities will be conducting tests to make sure that indeed this is Johanna de Haas who is buried on Vancouver Island. As soon as I see those results, I will update this post.
