The DuPont Bloodline.

There has been no consistency among the Du Pont family members in the spelling they have employed to write their name. The correct variations in spelling the Du Pont name are as follows: Dupont, DuPont, Du Pont, DuPont, Du Pont, and Du Pont de Nemours. In English the second syllable is accented. In French, neither syllable is accented. The name has tended to be spelled Du Pont for the family and Du Pont for business. I decided for this article to standardize the spelling in line with this tendency.
