I come from a family of 6.
Oldest brother is married -- twice to the same wife -- with 3 kids, and 6 grandkids.
Oldest sister is married -- also twice to the same husband -- with 1 daughter and 2 grandkids.
Next brother passed away last year -- leaving a wife, 3 kids and 2 grandkids.
Next sister is married with 3 kids, no grandkids, yet!
Then me.
Youngest brother -- single, no kids.
