For Palatine and other German immigrants the name fields don't seem to work very well since the middle name is usually the most important name yet sometimes isn't displayed in categories. Also the handing of the original German version of the name and the more commonly known Americanized version once they emigrate is inconsistent. If you put the Americanized version in the nick name field which seems logical you wouldn't see it in categories either. Basically in the categories you see profiles like "Johann Summer" and yet he is commonly known as "Adam". Actually there can be a bunch of profiles with the first name "Johann" since they is very common saints name.
Is there a style guide or standard way to handle German immigrant names? I have tried putting both the saints name and the rufname together in the first name field like "Johann Adam". Is that a good idea?
