An update:
I have not gotten my DNA results, but through the family tree feature on Ancestry.com I have gotten some fascinating information about my ancestors. I found that I'm second generation Welsh, and my father's first wife, who died, has family that is searching for information about my father. Also found out that my father had siblings who are looking for him and any family. That would be me. That means I potentially have family alive somewhere living about two hours from me.
Will I reach out to them? No, it would serve no purpose. But it is my heritage and is now backed up by fact, not just by stories diluted by time and memory. I also found more family on my mother's side that's withered away to nothing. I have to wonder if some characteristics in me were carried by past family? My father's people were Welsh miners and were tall and broad shouldered. My mother's side were tailors and accountants. I'm tall, have broad shoulders, sew and love numbers. It just sparks my imagination and frankly gives answers to questions I've had all my life.
