Trudy, you know that last stage of the merge process-- where you've got two columns and you're choosing which facts to keep? The "target" profile (in this case your "Unknown" profile) should always be on the right. That's an additional way to make sure that the merge is going in the right direction. If your target is not in the right-hand column, use your browser's back button to the previous screen and look for the "switch order" link (might be worded differently) at the top of THAT screen.
