I was watching Barack Obama deliver his speech for re-election at the 2012 Democratic National Convention, and found myself randomly looking at various information about his family and genealogy. I noticed an article in a 2008 Duvall family newsletter that described President Obama’s ancestor Mareen Duvall; this caught my eye as I remember Mareen Duvall in my own family tree, fairly directly through the Farley line.
I then confirmed that we indeed share the same ancestor – Mareen Duvall (the Emigrant) is our 9th-great-grandfather, which makes us 10th cousins.
