Answer 1

Answer:

Stephen F Austin brought in the "Old 300" and settled them between the Brazos and Colorado Rivers

Explanation:

Stephen F Austin was an Empressario who created Austin's Colony, which was the largest colony in Spanish Texas.  He granted the lands initially for 300 families creating the first colony of AngloAmerican immigrants in the area. They worked in rural activities as the lands near the river were cheap and suitable for this.
