Who was raised partially by his paternal grandmother because his mother couldn't speak English?

This is a nice triumph-of-the-human-spirit story. Hines Ward's father, an African American U.S. serviceman, met his mother, a South Korean cashier, outside a Seoul nightclub. A few months later, she got pregnant. The couple quickly married and Hines was born in 1976. They moved to the U.S. but the couple soon split. Hines went to live with his paternal grandmother in Louisiana because the courts had deemed his mother an unfit parent — due to the fact that she couldn't speak English and had no way to provide for him. Hines was 7 when finally reunited with his mother, but he wasn't happy about it at first. "I was ashamed of that side of my family," he said, "because I couldn't really understand. I had grown up around all black people before moving in with my mom, so coming into a predominantly mixed neighborhood, that was something that was new to me and something that I was ashamed of as a little kid." Now he is proud of his mother and the sacrifices she made for him, crediting her with his success today.
