My father is around 5 foot 6 my two older bros are 5 foot 8 ish but they are both more muscular with bigger bone structure than me, I am the youngest son and I am 6 foot 2 and a half just a shade under 6'3
But my mother is tall for a girl she is 5 foot 7, my uncles on my mothers side are all tall 6 foot to 6 foot 4.
Whats interesting with me is I was tiny my freshman year of high school around 5 foot 1. I grew to 5 foot 10 by senior year, and then grew to 6 foot 2 by the age of 20.
I have no clue if this helped me but when I was 14 I started sleeping in the dark I mean no night light nothing and would get 9 hours straight deep sleep. I wanted to grow so I was looking at stuff and this magazine suggested that young kids should sleep with the lights off it will trigger the growth process and also to get in nutrients and deep sleep
so I would stretch by doing dead hangs outside on the pull up bar we had for 10 minutes and then I would drink a tall glass of Ovaltine milk every single day before bed. I have no clue if that is what helped me grow, but I used to think so. But my Uncles were all late bloomers as well so I guess it had no affect but you never know
