No the only way for the evidence to match up was the DNA so they asked a relative to take a DNA test to see if it was him for sure and that was what confirmed it.
Well, it works fine to find relatives. But it's sad if you then find out those relatives have absolutely no idea of their heritage so you won't find out how you're connected.
But it's nice to upload the data to Promethease and see what kind of diseases may await you in the future.
I found it useful. It enabled me to break through a genealogy "brick wall" by connecting with a 3rd cousin who had more info on a pair of my (our) great-great-grandparents.
I'm not too concerned about privacy. I shed DNA all over the place just by existing, so I'm not really expecting that information to be private going forward.
There has been some controversy regarding the results of such tests. So, personally, I highly doubt the claims regarding what I can learn from a test, while I absolutely don't trust the companies doing the test, so personally it's an easy no.
