This line of descendants is derived from a family tree compiled by William Addams Reitwiesner, an American genealogist who traced the ancestry of U.S. political figures and other notable people. While Reitwiesner died in November 2010, his work on Obama’s ancestors is available at archive.org. Other Obama family trees are posted at FamousKin, ThoughtCo, WikiTree and elsewhere.
Family-tree information for Obama is also found in “Ancestors of American Presidents,” by Gary Boyd Roberts. The tree appears in the 2009 version of the book, as well as a corrected 2012 reprint.
The first generation of the family tree linking Dunham to Obama — Dunham and Mary Bloomfield’s 10 children — is shown below. Details are based on an analysis of multiple Dunham/Singletary family trees in books and online.
