this article dated 2004 would suggest that Malik-Roy-was 46 years of age when it was written in October of that year.
Quote from link:
“It was in the United States, in 1985, that he first met his 43-year-old half-brother Barack.
“...He was best man at my wedding and I was best man at his,” said Malik, who likes to point out that his younger brother’s name is actually Barack Obama II, because their father was the original Barack Obama...”
Well isn't that poorly written.
I finally found a reference that has Abo b. 1968 and Bernard in 1970. Oh well.
