I’m not really sure where to start, so I apologize if this sounds confusing.
A few years ago, I was talking with my grandfather when he suddenly mentioned that he had a brother, whom I had never heard about before.
According to my grandfather, his brother cut off all contact with the him in the 1970s for unknown reasons. However, their mother later told him that his brother had secretly kept up with his life during that time.
When their mother died in 2003, they reconnected and slowly started rebuilding their relationship.
At some point before that, his brother had been working in Africa, but later returned to Denmark and worked there for a few years before retiring at age 62.
A few years after retiring, when he was around 65, he went on a hiking trip in the Spanish Pyrenees. During that trip, he went missing, and no one in the family ever heard from him again. Due to the weather conditions in the area, the family assumed he likely died.
My grandfather passed away from ALS in 2023, so I can’t ask him anything more. However, he left behind memoirs for me, my sister, and a cousin, where a few pages are dedicated to his brother.
Now that I’m older, I really want to find out what happened to him — whether he actually died in the Pyrenees, or if there’s any chance he might still be alive and started a new life somewhere.
I just don’t know where to begin. Are there any resources, databases, or steps I could take to look into a case like this?
And what r/ groups are great for these type of things?
