Hannover and Dinwiddie County provide a contact list for civil Marriage Celebrants but I believe they are certified for the state and not just their county. Richmond, Henrico, Chesterfield, and Mechanicsville don't provide a list like this that I could find when I was looking 2 years ago. Congratulations
