Ancestry Member Trees

If you get hints to "Ancestry Member Trees", which contain information that you don't have/haven't yet found for yourself, is there a way of finding out which of the Trees was the one to post the info first - you know, the one that everyone else has copied from - or do you just have to look at them one at a time to see if you can find it?

Hope this makes sense!

Thanks
