Baptismal Name as Alternate Name in Other Information (below Vitals)
In “Other Information/Add Information/Alternte Names/Add Alternate Name”, add “Baptismal Name”.
Justification: German immigrants in the Itajaí Valley (Brazil) generally received a baptismal name quite different from the one they received in the Civil Registry.
At baptism, the first name usually consisted of the name chosen by the parents, usually, but not always, the one preceding the family name. This name in turn was preceded by other names, usually one to three, which honored the godparents. The names that honored the godparents, most of the time, do not appear in the civil registry. It is also frequent to use corresponding Portuguese names in the civil registry for the German baptismal names.
Including the “Baptismal Name” option would not only retain this information, but make it visible in the “Other Information” field (below Vitals).
The creation of the new option would certainly make it possible to avoid duplication of records and thus eliminate tens of thousands (probably much more) of conflicting data.
On the other hand, there is the alternative “Name at birth”, whose purpose/use I still don't understand. I suppose it is intended for cases of people who have had their name changed by court order.
