Today I think I've located another one: Bernard Dirks. Bernard was a native of Etzel, Ostfriesland, Germany who settled near Coatsburg in Adams County, Illinois, where he died in the 1910s. I really didn't "need" his passenger list, as his origins in Germany have been well documented. But it was a missing piece of the puzzle and one never knows what additional information may surface on a manifest.
Bernard's two census enumerations where immigration information is provided both indicate an arrival year of 1852:
- 1910 US Federal Census, Honey Creek Township, Enumeration District 12, sheet 4B
- 1900 US Federal Census, Honey Creek Township, Enumeration District 109, Sheet 6B
After some additional time spent with wildcard searching at Ancestry.com I discovered a "Bernard Dirks" having arrived in New York in July of 1852. This was the only reasonably close match that I was able to locate performing a wildcard search with vowels replaced by wildcard operators.
I'm as certain as I can be at this point that this is the entry for "my Bernard." It is known that he immigrated before he married and, to date, no relatives of his have been located in the United States so his arriving without other Dirkses isn't unusual.
