Decided to give Ancestry Help Line a call on this one. They had several useful things to say that I thought I would share here: 1) They indicated that they are very behind in updating everyone's match reports. They have had significant response to the test offering so lots of results to post for everyone. Yay! 2) If after the reporting has caught up, I still do not appear in her DNA results then it does indeed raise the probability that the report of her on my list is a false positive.
