New Site for Finding Vital Records Offices
There is a new page from the State Dept of Health and Family Services that lists local vital record-related services (including Clerks of Court). It includes PDF files for the Clerks of Court listing and map, and links to lists of current county fees for marriage licenses and Coroner/ME fees. It also includes lists and maps for Registers of Deeds and Milwaukee and West Allis offices, County Clerks, Clerks of Court and Coroners/MEs.
FYI: I found out from the info on this page that Dane County has the highest fees in the state for obtaining a marriage license.
