Online genealogy research in Iowa can be greatly enhanced with the usage of County History books. These types of manuscripts normally contain a section devoted to the history of the county, from the time the Natives resided there, until the time of publication. Most of these county histories were published during the late 1800's and early 1900's and many of them are now available online for free download and reading.
