I am 5th generation born in Texas. We can trace our family coming into Texas in ~1828. Based off of research he was granted land in Brazoria on the Brazos. By Mexican decree, they were forced inland to another Leauge of land near present day Matagorda. I have located both plots of land on historic maps.
A couple of years ago, I found a transcript of a letter to Stephen Austin introducing my GGG Grandfather. See link below.
https://texashistory.unt.edu/ark:/67531/metapth216632/He was involved in an event at Washington on the Brazos called the Consultation and he was charges with gathering a militia for the Brazoria region.
Unfortunately, we cannot verify his death year as family records were destroyed in the aftermath of the Revilution. My GG grandfather (born 1830) lived in Washington with his uncle
