Land records for Fond du Lac county, are found in the Register of Deeds office. http://www.rootsweb.com/~wifonddu/resources/vitals/regdeeds.html There is a grantor-grantee index to land transactions, which is very helpful. The people in the office do NOT do genealogical research, and I do not have anyone right now who volunteers to do look-ups for county research. Tracy
