Stephen, my example to you was hypothetical with no real persons names, so where you got the maiden name Simpson from I don't know. I wanted you to try to find a girls ancestry without having the maiden name in the profile, which you obviously didn't understand. Are you able to do that?
I am not. On the other hand, I'm quite able to find the same girls descendants without having the girls name after marriage in her profile, since I will find that name in her husbands profile.
You just proved to me that you couldn't do it without the maiden name. Now tell me which name is more important.
I can see that you don't understand this, since you stick to your display argument, this hasn't anything to with how things are displayed, this is genealogy! And it's not only my 1000 profiles that are using the system of genealogists, it's almost every profile of a person living in Northern Europe before ca. 1900, and it's almost every profile added by a person using the system genealogists are using.
And, I'm sorry to say, there is no consensus, and there will probably never be one. There are too many on Geni that want to write names like genealogists do, and there are too many people that write names in other ways.
I hope Erica reads your comment about birth certificates, since she is adamant in arguing that she has problems finding maiden names in birth certificates.
