I'm too damn tired to do the math but since I read that Rainman was bumming because Psi's thread was thrashing his I thought I'd try and help.

I am not capable of completing this excercise on my own. Way too many cousins that I have not met. :)

I'm the tenth oldest out of 37 total cousins and siblings

4th of 32

3rd oldest on my Mothers side.
2nd oldest (by 2months 15 days) on my Dad's.

My son is the third Grandson on my Mom's side, but is the oldest one on my Dad's side.

Ditto...

I'm the fourth youngest out of 13 cousins. Range=25-60; Mean=41; Median=45;

16 kids on my Fathers side,18 on my Mothers side,and I have cousins I have never met
I wouldn't have a clue on how many.
my mother was pregnant with me, and at the same time my grandmother was pregnant with my uncle, he's about 2 1/2 months older than me.
