Thoguht I'd start by *almost* confirming that DS2 will be Simon Thomas. I'm pretty sure. Almost totally sure.
And if my step-sister I almost never speak to who is due a few weeks after me tries to chat about names one more time, I'm going to scream at her. Probably a lot. Expecially since she's having a girl, and I really don't care if she names her kid Simon Thomas as well, the kids will rarely see each other! I hate people getting posessive about naming "right." Gggrrr.
