In the end, it turns out that all the research in the world can't take the place of pure dumb luck. In the end, what eventually enabled me to find my birth family was a fluke, a joke, a serendipitous chain of events that yielded me results I might have otherwise never reached.
In the end, it didn't matter how I found them but that I did find them, those mysterious shadow people, those biological parents, MY birth parents.
