How do I calculate my family's "average family location"?

So, I just listened to a This American Life podcast called Ghost in the Machine. In one of the stories, a man decides to calculate, every week, the Average Family Location of his family. By that, he means: once you add everyone's coordinates for every coordinate in which they've been in that period, what city/location represents the average point between them all?
I decided to do the same for my family, which will be much easier because there are no touring musicians among us. The one complication is that a good chunk of the family is on other continents, and I wouldn't want us to "meet" in the middle of the ocean. So some approximation might be warranted.
I'd be happy if someone could provide me the math, I'm fairly confident I would be able to do it with a calculator or maybe put into some crude Python. I don't think I need to make a weekly report, since we're not that mobile. Maybe twice a year, or once every two months.
Thanks!
Edit: I don't know much math
Edit2: holy shit this is not simple at all! Now I feel kinda bad for throwing this problem at you guys. I really thought it would be quick and easy!

So, my 5-year-old nephew is obsessed with huge numbers, especially named numbers such as googol, duodecillion, and centillion. The other day I spent some time reciting these numbers to him, and trying (and failing) to describe them. What I need are some cool facts about these numbers, such as "there are 1 quadrillion cat hairs in the world", or "there are not enough stars in the universe to fill one googol".
Besides math, his main interests are super-heroes and, apparently, cars.
I'm not a math or physics guy, so hopefully you guys can help me cheat :P

I recently began thinking about how plants get their shape and discovered "morphogenesis" after some inept googling. It seems like a fascinating subject so I'd like to learn a bit more. I have some A-level university courses in chemistry and microbiology, but never dug too deep. So I am looking for suggestions on what to read up on in order to gain some understanding of how plants and other organisms get their shape. The ultimate goal is of course to plant my own house.
