During the 2006 election, it was brought to attention that Reinfeldt's paternal great-grandfather, John Reinfeldt, was the illegitimate son of Emma Dorotea Reinfeld, a maid from Eckau in present-day Latvia, and John Hood, an African American circus director from New York.
So if this is the case, the article is indeed correct.
Okay, but you know, I’d bet they’d have called him African American regardless of where he was from! (but thanks for the clarity!)
It doesn't say that John Hood was black. He could have been the white director of a circus owned by some African Americans.
