Indexing other family names
In project: US, California—Naturalization Records, 1903–1991 [Part A][MQFS-HKM]
It mentions not to index anyone else on the document outside of the principle person. This would include NOT indexing spouse or children that may be mentioned on the document. Can someone confirm to me if my understanding of this is true? And if so why? It seems as if I have indexed those other names in other projects, and I don't understand why I wouldn't here. It even mentions to NOT create a separate record for those people although there is an additional blank entry for each entry in every batch.
Could someone explain and confirm this for me just for additional clarity and insight? Thanks
