'We're a family'published at 13:24 BST
Mr Wray says his brother, who was "dearly loved", was shot twice in the back.
"He was a lovely human being."
He says younger family members didn't know James "because he was dead before they were born".
Today is emotional, Mr Wray says, because "it takes you back to the horror of [Bloody Sunday]" - to "the wounds Jim had, the situation, the fear, the terror..."
"But we'll hold up together," he says. "We're a family."
