Earlier today I posted the new announcement by Ancestry.com describing the company's new online Immigration Collection database. I will repeat the third sentence of that announcement:
To commemorate the launch of the collection, Ancestry.com is offering completely free access to its entire Immigration Collection through the end of November.
Keep in mind that the free access is only to the new Immigration Collection but that certainly is a great offer.
The Immigration Collection is available at http://www.ancestry.com
