I LOVE Lauren. As for girls, I have a ton of names since I'm on my 3rd boy
Alyssa, Alayna, Maya, Tessa, Brianne. Hmmm, I'm forgetting some. I have a friend expecting a girl and I gave her a list of about 20 names a few weeks ago. We're trading names that we can't use for our own babies. She gives me any boy names she comes up with and I give her girl names!
As far as shortening names. My husband is Jon. Not JOHN, not Jonathan, just JON. Besides everyone wanting to throw in the H, they assume it's short for Jonathan since it doesn't have the H. It drives him crazy too! I love the name Andrew and hate Andy. I used it as a middle name so no one will ever shorten it! We have Grant Calvin (my Grandpa died while I was pregnant so he got his name as the middle) and Jared Andrew. Neither one of those can be shortened.
As far as boys, I'm watching the thread for names. I have a few, but none we agree on- Elias, Canaan, Dylan (Grant's backup), Evan, Heath, Derek. (I think they only reason he doesn't like Derek is because Grey's Anatomy is my favorite show and thinks I got it from there!)
