Against all odds!

My mother died of a very unusual disease (CJD) - one in a million is the likely hood of you to get it. As it is so unusual I wanted to get connected with other families who lost loved ones but there are no one to be found and the hospital of course cannot give me their names. I have only found CJD Families in the US and the UK but not here in Sweden.
As I am emptying my mothers apartment I am selling her things to people in the neighbourhood where I live. A very nice woman came over to my house 3 times to buy things and she saw on Facebook that I wrote about the disease CJD. So she wrote to me and asked if I had a relative who passed away from CJD. So it turns out that I found a relative in my own hallway!!! What is the odds for that!? She lives only 1000 meters from me!
