Correct.
I felt no need to memorize Obama’s lineage.
Still don’t.
Has anyone checked Ancestry.com? I don’t have a membership.
You don’t need to memorize his lineage to know that his grandfather’s name was Stanley A. Dunham, the same as his mothers. For pete’s sake, it’s been in the news in 1000’s of articles for 2 years. I would have thought somewhere along the line you would have known that.
