I'm the tallest in my direct family (Mom, sister, Dad).
Extended... I'm the 5th tallest. My cousins range from 6'4" to 6'8". That's 4 people. Then one uncle is 6'5".
The funny thing is, on my dad's side, the guys are all really tall, then my dad's sister is 5'1" and her daughter is 5'2" (well below average)!
