Bill,

An implied promise of historical accuracy was part of my original attraction
to being DNA tested, one which completely eliminated any need for written
family records, if such records could be anywhere near accurate and if such
records even existed at all. Great! Or so I thought.

OK. I was wrong. There are gaps and a paper-trail is still considered a
necessary part of family research.

But DNA-based family research really is an amazing technology, well worth
doing.
