Thats on his father's side, were as his mother is English born with English roots. I raised the same question last month. Though still a good question.
I remember when you couldn't find 3 Americans who knew what the Tour De France was. Then Greg LeMond and Lance Armstrong came along and the visibility of bicycle racing in the US rose dramatically. If an American was winning in F1, particularly a black American, then it would be all over the press.
LOL!! England is not America my friend. The term African American is directed at some one who is of colour born in America of FULL African descendancy in there family line. LH is BRITISH born in ENGLAND with parents from two ethnicity's. Farther of Caribbean (black) descendancy and mother from English (white) descendancy. Not all people of colour of the world are African American
