Thanks.
Update: Sadly, NJ requires both the month of the marriage and the county. I have neither. So, I called the reference office and left voice mail. Hopefully, I can get this done soon.
If anyone is near enough to the archives to look it up and provide me with the names of Helen's parents and their location at the time of the marriage, I would happily pay you the $10 fee.
2nd Update: I contacted the NJ State Department and was told that I could put anything I want in the County and Month fields, and if I provided the certificate number, they would ignore those fields. I have ordered a copy of the license.
