NARA and Sittin’ in a Tree... has signed an agreement with the National Archives and Records Administration (NARA) to extend and accelerate their digitization efforts. Ancestry already has a huge treasure trove of NARA records online, including census, immigration, and military records. I’m looking forward to seeing what’s yet to come.

To celebrate the agreement, is making their entire Military Records Collection available for free from May 20 through May 31. This collection includes the Marine Corps Muster Rolls I used for my investigation into my grandfather’s military service.
