The following databases are showing on FamilySearch as updated or new:
Michigan Obituaries, 1820-2006
Oregon, Yamhill County Records, 1857-1963
Minnesota, Grand Army of the Republic Membership Records, 1869-1940
Nebraska, State Census, 1885
District of Columbia Deaths, 1874-1959
Note: Nebraska State Census must be an update of sorts because it's showing as a viewed link for me. The others may be updates as well, but I don't have any personal interest in those time periods and locations.
And I'm wondering just what newspapers were published in Michigan in 1820, but that's a whole separate blog post (grin!).
