Having read the proposal for South African 'Afrikaans' Profile and the SA tree, please could I ask if the concept of "Legal name at birth" and "Legal name at death" have been considered instead / in addition to last name, maiden name, married name? There is no reason all of these options can't be used on a record,. They are just data in a database that become searchable to the seeker, available for selection in a report or output per personal preference.
Similarly, capitalising surnames appears to be of little significance, as caps and lower case are equally searchable. It only makes a difference in appearance in reporting, particularly in source products like Brothers Keeper where much of Geni data may have originated from. I see no relevance in imposing mixed case surnames as a regulation.
Genealogical numbering is not commonly understood amongst family tree fans. Imposing this as a requirement to satisfy the genealogists may crush the initiative of enthusiasts loading their trees and enriching our data store, but ist is simple to provide a field for supporters of this numbering to add that data to a record?
Source documents are invaluable, but extremely difficult to find in every case. Again, an optional source field should be available on a record for those source documents that exist, or simply an "Is this persons record verified by source documents attached" indicator for the puritans, and attach scanned birth certificates, etc, as pictures. Imposing a requirement that ALL records are only made available in Geni if supported by source documents would invalidate the larger proportion of data in the database.
