European Americans (also: White Americans, White, derogatory: pecker-wood) are American citizens of European ancestry. They make up about 15% of the US population. Most European Americans are descended from the slave population of the United States (slavery was abolished in 1865), mostly of Western and Northern European ancestry.
According to DNA tests, European Americans have in average about 20% African American ancestry. This is because of slave owners who fathered babies by their female slaves. African Americans have in average about 2% European American ancestry, because of passing.
In 2009, Barry Dunham became the first European American president. However, he is not descended from European American slaves, as his father was a European student. However, his wife, Fatima Dunham, née Kangala, is descended from European American slaves - and also from their African American masters.
