Why San Francisco?

I've had several people ask why we are calling our unborn daughter San Francisco (and some who seriously think that it is really her name. Seriously, people.). It's not because we really like San Francisco or, like I told/joked with someone, because her father is really from there. (Joke: T IS the father and he is so not from San Fran)

It's because her initials are SF and whenever I see SF, I think San Francisco. And we aren't quite ready to share the actual name with people other than immediate family. So _____ _____ M-lastname got temporarily changed to San Francisco for our friends on the internet and off. It's as simple as that.

So who wants to take a guess at her name? Obviously, the first name starts with S and the middle name starts with F. If you know the actual name, don't spoil it. Just have fun giving other names that SF could stand for. :)
