One of our arbitrators sent me the following which definitely applies to our marriages. Please read it and use it in your indexing.
"Mar/Apr 2007 Family Record Extraction Memorandum
Sometimes a name is recorded more than once on the same historical document. For instance, on a marriage certificate the name of the groom may appear in two or three different places. In one place, the name may be written as C. H. Johnson. In another place, it may be Chas. H. Johnson. And in still a third place, the name may be written as Charles Henry Johnson.
Please take time to scan the entire certificate and type only the most complete version of the name. This will increase the chances of a researcher finding the name of an ancestor in the index."
