I'm the tallest in my family (no troll) as far as I know.
I turn 17 in 12 days and I'm 5'11, 180.3cm on the dot.
My mum is like 5'4 and my dad is like 5'6.
I have no uncles (on either sides) or grandpa's (on either side, even my own parents barely knew them).
No-one understands where I get my height from since I come from a family of midgets.
I take pride in it though.
