Any European American with American Indian ancestry, however slim or unverified, is eager to share this knowledge with nearly everyone they meet. African-Americans, most of whom have 15 -20% European ancestry, almost never acknowledge this.
I find it interesting that while the Spaniards mingled with the Central American Indians they conquered, such that most Mexicans are of mixed ancestry, the northern Europeans killed and conquered but seldom mingled with the American Indian population. It strikes me that this is the difference between the military and religious conquering of the Spanish and relocation/settling of the English. The Brits brought wives and sons and daughters, the Spaniards brought soldiers and priests and left their women behind.
