Since Geni is a user genealogical site it should be useful to the user and a Geni profile should reflect the the connections in the path as much as possible with due respect for the people in path. I recommend the naming form
<Firstname (Surname) Lastname>
for females, and for males who had a name change. In the case where there are multiple marriages, there also needs to be a robust way in notation to reflect the changes, e.g.,
<Firstname (Surname) Lastname1 - Lastname2>
etc. (assuming Surname = Lastname0). This would extend the utility to other users those connections in the multiple marriage case follow a different last name. This would be useful for determining the cousin information from the typical Geni sibling connection when the siblings share only one parent in common.
I get a lot of questions from other Geni users about confusing similar names and connections, and when I can I usually clarify the profile naming to avoid problems for future users.
