One of the recently added databases at 
Ancestry.com is the complete set of Iowa state censuses. The image in this post comes from the 1856 state census for Scott County, Iowa. This entry is actually for Peter Freund, but the name was spelled Frent. A soundex search easily caught the entry. An upcoming article in the Ancestry World Journal will discuss using these wonderful records for the Freund family. Meanwhile genealogists can be searching for their Iowa ancestors in this Ancestry.com database.
