According to Jonathan Miller's book "Stripped: Depeche Mode" (Omnibus Press, 2003, 2004, ISBN 1-84449-415-2, pp. 318-319), Gore's biological father was an African-American GI stationed in the UK. Gore was raised by his stepfather and biological mother. Miller quotes childhood friends and Gore himself. According to Miller's source, Gore is of mixed ethnicity, and, as an adult, met his father in the American South. Gore responds to the source's information and is quoted in Miller's book saying "It brings up family traumas" and "It's one of those things I'd rather not talk about."
