Basically I am wondering whether to try to contact some people and would like to hear advice/stories from anyone who has done similar, or anyone who has themselves been contacted. What went down well? What didn't? Was the contact welcome?
In short, I was in my 40s before I found out (via a slip of the tongue) that my dad had an adopted brother, with whom all contact had been severed. That generation of the family is now all dead, but after years of searching I believe I've identified the adopted brother's children - who would be my adopted cousins, but not blood relatives of course. I believe that 2, maybe 3 of them are probably still alive and will be in their late 60s - early 70s now. I have no idea if they even know of my side of the family or if the family fracture was so complete that their side of the family never knew that my father married and had children of his own.
The situation is possibly complicated by the fact that I suspect (from newspaper reports) that my father's adopted brother was charged, as an adult, with a serious crime. I don't think this incident was the cause of the fallout between my father and the brother because the split in the family seems to have happened many years before, but it might be something that is best kept buried.
So, any advice or stories that people can share? I can't decide what to do. It's only curiosity, after all, that makes me want to contact these "adopted cousins". But it's only curiosity that drives any of us to do the family tree in the first place, isn't it? WWYD?
