Amazing stuff. Seems to me more important to understanding your ancestry than any 23andMe report could prove. I wish I had a similar source of info, but I don’t think they recorded who was working at which silk looms in New Jersey way back in the day.
You never know what you are going to find. I had no idea that both of my Mom’s grandparents were homesteaders in Manitoba, Saskatchewan and North Dakota. I’ve always wondered about where her family came from. One side of the family came from England and one side from Germany. My dad’s family is all from Germany. Interestingly, the two families lived less than 200 miles from each other in Germany.
I’ve done the DNA tests and they really haven’t told me anything useful. One woman in England did reach out to me and we had a fun email conversation going on for quite a while. We share a common ancestor in England and are both doing genealogical research.
