There's some fuss right now that Obama was playing golf instead of going to his aunt's funeral. Actually, Auntie Zeituni has caused him a lot of grief as a free-loader and law breaker who needed the Bush administration to pull Obama out of a mess with her in 2008 (a lot of thanks he got). Bush officials issued a 72-hour cease-and-desist order to all fugitive apprehension teams to spare Obama embarrassment over his auntie right before Election Day when it came out that she had been living illegally in the U.S. for some years, and had evaded a 2003 deportation order.
And look, his Kenyan father was a polygamist, as was his father, so she was only a half aunt in a family full of halves some with their hands out for a favor, expecting "my brother's keeper" treatment. Still, one of his half brothers, Malik, who is not a millionaire, managed to make it.
For his book and his political career, Obama's African family was useful when need presented itself. " A delegation of African relatives flew in for Mr. Obama’s inauguration in 2009 and received royal treatment." http://www.nytimes.com/2014/04/23/us/politics/amid-politics-obama-drifted-away-from-kin.html?_r=0
