For those of you who saw my post about Seeking Michigan uploading images of the Michigan 1894 census, I have good news. There are now images for at least 22 counties available. They are as follows: Barry, Bay, Hillsdale, Ingham, Iosco, Jackson, Lapeer, Lenawee, Kalamazoo, Kent, Keweenaw, Menomenee, Midland, Montcalm, Muskegon, Newaygo, Ottawa, Roscommon, Sanilac, St. Clair, St. Joseph and Wayne.
It is possible that other counties are also searchable. To determine which county's images had been uploaded I searched for the surnames Smith and Brown, hoping that there was at least one person in each county with one of these all too common names. If you are searching for someone in a sparsely populated Upper Peninsula county, for example, it may be worth checking in case no one there bears the Smith or Brown moniker.
Images for Washtenaw county were briefly available, but were hopelessly blurred such that they were completely unreadable. Washtenaw county no longer appears in the search results so I hope that means the problem was detected and is being addressed.
You can start your search on the 1884-1894 Census page to see the images that are available.
Update: April 2013. Seeking Michigan is currently adding census images between 1827 and 1874. To see what records we can look forward to see my post.
