[Verginius Rufus]

Cabeza de Vaca mentions an Indian tribe in Texas which killed all of its girl babies at birth, and acquired wives from other tribes.

[Verginius Rufus]

The Indians who practiced female infanticide are called Mariames (or Marianes) and Yguases by Cabeza de Vaca. They apparently lived roughly in the lower Guadalupe River valley of Texas. He says none of the other Indians had this custom.

In the Penguin translation, Alvar Nunez Cabeza de Vaca, Chronicle of the Narvaez Expedition, this is mentioned in chapter 18.
