Maryann:
First of all, your answer was very helpful in highlighting the capabilities of the system. My concern was with simplifying the search capabilities, though. If you look at the list of volunteers, every day large numbers are joining, and they don't know the intricacies of the program yet, but we can safely assume that they all create profiles to some extent. An American descendant of Czech immigrants may create a profile for a Novotny which will not be matched with the same Novotný already in the system. Women from cultures with distinct female forms of the name will not match, and in that case using the Other Name field for the male name form would be wrong since they were never also known as under that name.
I just felt having a field for searches that does not show up on the profile page would make those profiles much less cluttered. Ideally, it would allow to create a profile for Dvořak and give me the potential matches for all the Dworschaks, Dworzaks, Dvorzaks and their female forms without having all these spelling variations show up as aka names.
