Ohhh I like this thread -- wish I had time to create an image (maybe I can in a littile while...).
I believe his first child would be a boy (for many 'practical' reasons -- help Dad on the job; etc.). Then they'd have a little girl. Then -- after at least a 10 year break they'd have twins (boy and girl) -- and finally a "surprise" girl child with wild red hair who would be kind of like "Grace" in personality. I thought her up many years ago, and got a kick out of Grace in the movie, as I picture his youngest child being a real "handful" -- kind of like a non-evil Atlas.
Yup, five kids, that's what I envision!

- I better have a good job!

- I'll see to that!
@Acorn -- I LOVE "little Cora!!"
