Luo names follow an order pattern of (1) a Christian given name (these used at least for the past two generations), (2) a personal surname (selected from among over 50 “special” attributes, usually relating to the circumstances of a birth, see below), and (3) a patronymic, the child’s father’s personal surname (a woman assumes her husband’s at marriage). Thus, e.g., Valentine Odhiambo Pengo or Philomena Ogwang Odede.
The commonest Luo “personal surnames” are as follows (O- always indicates a male; A- indicates a female; about 85% of Luo names include one of these). The meaning is indicated, when well known and accepted.

Surnames (last names) are a western convention. They didn't have them. Remember when the brother Omar was found in Boston? He had arrived to attend a private high school (don't ask who paid) in either 1962 or 1963, he lived with the kenyan student at 170 Magazine Street. His name was Omar. Omar Obama Onyango? He calls himself Obama Onyango now. I'm not even going to try to follow it. All the children of Kezia start out with names like Grace and Rita and Roy and Bernard etc...and now the all have Arab first names.

Roy Malik has taken the name ‘Abongo’. According to this article, that means he’s a female. Something amiss somewhere. Also according to your source, his name means ‘only child’. Doesn’t he have a sister and a bunch of half brothers?
