Lynda is right, the question is a little vague. As I would interpret it, I think you are finding that some of your ancestors already have profiles here. That's not unusual. The older ones are most likely 'Open' privacy and can be edited if you have info to add. Those of people born less than 150 years ago or who died less than 100 years ago may have a higher privacy level, and you would need to get on the trusted list to edit those. I hope you are not saying that you have uploaded thousands of profiles that duplicate the ones that are already here, because that would mean that you may have to spend the rest of your life dealing with merges.
