The record owners have specified what we are to index, so it is not a problem.
When researchers are brought to this image by the index we are making, they will see a lot of extra information and also can scroll back and forth on the film to see relevant adjacent images.
Also, I'm currently indexing "US, Missouri, Various Counties— Obituaries, 1880–1990[M36M-1HQ]" and noticed that although quite a few obituaries include the names of the deceased's great-grandchildren, there is no option for entering in the names of their great grandchildren.
Every name is indexed on Obituaries. They great grandchildren are indexed and the relationship is grandchild, or grand-daughter or grandson if the distinction is made to determine gender.
