Well, I definitely got the spelling ability as well as the spatial thing, neither of which my spouse has, but our DD has the spelling ability but not the strength in the spatial domain that I have. My handicap in digit span more than makes up for it. People seriously do not believe me that I can't even keep a phone number in my head long enough to dial it or write it down, but it's true.
I can memorize LONG digits when I use them often enough to commit them to long-term memory, though. I know my library card number (16 digits) by heart, for example.
Once I've been to a location, I have it "mapped" in my brain, though-- it's another savant thing that I can do, I guess. I am not entirely sure how I do it, but I get that one from my mother.
DH teases me that I was clearly a migratory songbird in another life.
