Very true. Given that kind of a case, such as when a genetic father is a
brother or cousin of the father of record, you could indeed have a situation
where DNA won't make the call. (OTOH, the impact of such on the
'traditional' family tree would be minimal.) I was thinking in terms of
the more straightforward case where the two (DNA and paper trail) simply do
not agree with each other. In that case it's my opinion that the DNA
wins.
