Rockefeller entry.
Hello Paul, thanks for your message. I need to explain myself. On WT:CFI#Genealogical content, our policy page about what words and definitions to include, it says, "Wiktionary is not a genealogy database. Wiktionary articles on family names, for example, are not intended to be about the people who share the family name. They are about the name as a word." So I think that the Rockefeller sense about the family itself would fall under that criterion.
Why is Freud an exception? (Also Einstein, Jefferson, etc.) I'm not sure, but it could be that the surname itself is commonly used in an idiomatic way to refer to one particular individual, and not just any old person named Freud. This kind of usage seems marginally acceptable in my opinion, but talking about the whole family of Freuds would probably run afoul of the WT:CFI.
John D. Rockefeller, founder of Standard Oil, is almost as well known as Freud. Is adding an entry about him ok, as long I don't turn it into a geneology? It would be along the lines of Freud, Eintstein, Jefferson, because he's so famous.
It's a tough call. Place names, people names and company names have always been a controversial topic and I'm not sure how I feel about them. I say go for it, as long as it doesn't look like a genealogy and as long as what you add otherwise meets CFI. I can't guarantee that someone won't put it up for verification and/or deletion though.
