re: The marriage license fee re the marriage of James Adair to Clark Hobson, St. Stephen's Parish, Northumberland County, Virginia, is recorded in Fee Book 1740-1742, which is indexed. That's on Microfilm Reel #74 (for Northumberland County) at the Virginia State Library in Richmond.
Thank you Gwen, nice to hear from you. Happy New Year from an extremely hot South Australia.
If anyone goes to the Library in Richmond, let's hope they are kind enough to pop in and check.
