Article on Tacko Fall. His parents arent tall and his dad lives in Cincinnati with Tacko's 11 year old brother who according to Wikipedia was 5'9" at 7 years old.
Tacko has only played basketball for 4 years now. If his brother is over 6 foot at age 11, Id assume hes already started playing a little basketball himself.
