Sue, the "marry small" thing might not work out so well. I have a feeling that small is recessive.
A few cases in point:
Although I come from the Lollipop Guild, genetically speaking, I have Size 10 feet courtesy of my outsized father. The one giant in the pack.
My husband is, in his own words, a Great Lumbering Man. He married small (well, except for the feet) So far, the children are all HUGE. With HUGE FEET!
So...
one tiny wife + one giant husband = 5 gigantic children. All with big feet.
