Scottish involvement in the Texas History - John Cameron's Grant

[Cameron of Texas]

A friend of mine and local printer was looking over early (pre Civil War) maps of Texas. He brought to my attention something that blew my mind - The part of Texas in which I live was once known as John Cameron's Grant...and my name is John Cameron. What blew my mind is I've lived in Texas for over 20 years and had never heard of this slice of state history.

The short story is : John Cameron, early settler and soldier, was a native of Scotland. On May 21, 1827, the Mexican government granted him an empresario contract to introduce 100 families on the Colorado River in Texas.

Does anyone here know of John Cameron or other Scotsman playing a role in Texas history?
