Ancestry.com's blog ran my "torn manifest" article yesterday and it can be viewed in a printer friendly version on their site. It analyzes the manifest, discusses how I made my way around the "tear" as best I could and additional follow up that needs to be done.
Andreas Schulmeyer is my wife's 4th great-grandfather and he died after the 1870 census, likely in Scott County, Iowa. The line of descent is as follows:
1) Andreas Schulmeyer
2) Elizabeth Schulmeyer Freund Wachter (1840 Beberstedt, Germany-1899 Davenport, Scott County, Iowa)
3) George A. Freund (1858 Davenport, Iowa-1928 Davenport, Iowa)
4) Caroline Freund Mortier (1884 Davenport, Iowa-1981 Rock Island, Rock Island County, Illinois)
5) Grace Mortier Johnson (1913 Bowling Township, Rock Island County, Illinois-2000 Rock Island, Illinois)--my wife's paternal grandmother.
I'd be happy to hear from anyone researching the Schulmeyers in Scott County, Iowa.
