Although I have read the style pages, I am not certain what is considered standard when I run into a gedcom-created, auto-generated bio or when a merge has created multiple duplicate info. I try to rewrite them clearly when I encounter them. Herr's what I try to do. Corrections or suggestions are welcome.
First, I move all the duplicated info from merges into a single ==Heading==. So if there are multiple ==Sources== sections, for example, I combine them.
Then I delete anything that is clearly duplicated.
Then I rewrite the sections to make them readable. I will delete, for example, something that says "Date: " or "Place: " with no actual information.
Then I will delete any useless references to Ancestor.com sources if I have a better one to replace it. Even Geni and FamilySearch are more useful since you can actually find the source.
Do you think this is a generally reasonable procedure?
