I clicked on the first record and was brought to the page below, requiring registration to view the record. Again I clicked "No thanks," but was returned to the list of results and not the actual record.
With my paid account, I searched for "Ezra Dunn" born in New Jersey and returned over seven million records. (Over 99% of those records are irrelevant, so more specific search parameters would be more helpful.)
If anyone tries out this free access, please let us know what record types from which countries result. Someone told me that a credit card is required for Free Access, which people are understandably hesitant to provide for a free service.
If this is truly free access to all of Ancestry.com, then you have a great opportunity to explore the site to see if continued access via paid subscription could help your research.
