So I talked to my brother and his whole family (wife and 2 daughters) last week via FaceTime. It was awkward as hell, of course, but other than that it went really well. He doesn't speak much English, though he seems to understand pretty well, and the oldest daughter had to do a lot of translating He tried for a long time to find me, but was going through refugee organizations, and I was never a refugee, so none of those organizations had any record of me. He gave up years ago - before the internet really took off. His daughter found me on the internet in less than an hour - I am easily searchable by my full name for this very reason - I have wanted to be found.
And, my gods, this sounds so trite ... but I feel as if I have indeed been found.
