Please look at the possibility that we need:
1).MULTIPLE GENERIC (ie not CULTURE-SPECIFIC) FIELD OPTIONS which allow us to enter all (or at least more) of the possible naming convention data that we encounter.
eg
birth surname:...
first spouse's surname:
second spouse's surname:
etc
in a way that acknowledges that geni users are not usually expert genealogists, but are still expected to merge profiles, and therefore need the most info that can be provided to avoid mis-merges.
(Display conventions may be the next discussion that needs to be had, but cannot logically precede the programming of input data discussion.)
2). THE DISPLAY NAME FIELD MAY BE ANACHRONISTIC in that it may contradict people's ability to set their screen view to show maiden or not maiden etc conventions
