MASACUAJULAM INDIANS. In the middle eighteenth century the Masacuajulam (Imasacuajulam) Indians lived along the lower Rio Grande somewhere between the site of present Zapata, Texas, and the mouth of the river. The maps of Jiménez Moreno and Saldivar show this group on the north bank of the Rio Grande in the area of present Zapata County, but the known documents do not permit such a precise placement. The name is said to mean "those who travel alone."
