A baby? Congratulations!
I've always had a soft spot for the name:
Cheryl.
But here are a few more...
1) Alyssa
2) Mikaela (The spelling's weird, but it sounds nice. Mikaela Lim right?)
3) Erin
Can't really think of a guy's name. Sorry, 'cos I prefer daughters to sons.

BTW, Sarah means "lady" in hebrew.. I think ... derived from Abraham's Wife (Read Genesis)
