I was alerted to this on another list, which said the offer was for 16-19 August. I cannot confirm this from what I've seen on the Ancestry pages. Forget all your plans, and spend the next three days gathering data that you wouldn't normally have access to! :-) Don't forget to use Ancestry's "My Ancestry" tab to record your tree so that they can suggest connections and data you may not have seen before, including census pages. It's free to use this section at any time. Wendy
