Excerpts from the DeWitt Colony John Henry Brown History of Texas:
"Without saying who was the first settler in what is now Lavaca County, it can be said that between '30 and '36.....Andrew Kent.....Adam Zumwalt....all settled on or near the Lavaca from the "kent" place about ten miles below Hallettsville, to a point perhaps twelve miles above.
After the retreat in '36, very few persons returned to Lavaca County. Zumwalt, Heath , the Kent family, ....and others returned so as to plant crops in 1837."
Capt Adam commanded "the Lavaca River area minuteman company in most, if not all, of its actions in maintenance of the security of the area including the Comanche Raid on Linnville/Battle of Plum Creek and Battle of Salado."
County records show Adam's livestock trades with other locals.
1840 Where was Adam that year?
11/14/1850 Peach Creek, Gonzales Co, TX. By the next census the family had moved, following other Zumwalts to the wild west. Adam was 55 years old and his property totaled $3800. Wife Jane J was 50 and the children were Mary, 16, and Gabriel, 14, as well as Jane Gannal (sp?), 10, and Nancy Gannalt, 8. Down the road were Thomas and Isaac Zumwalt. Sons?
7/20/1860 Fayette Co, TX near Plum Grove. On the move again that year the census recorded Adam at 65, Jane S at 60. Adam's estate was worth $2000/4900 and he was still farming. Living with them was the family of son Gabriel.
11/8/1870 Between Halletsville Rd and Buckner Creek, Fayette Co, TX. That year Adam was listed in the census at age 75 but still farming. His property totaled $4000/1200. Apparently he had a second wife as her name was Clarissa, 60. Living with them were Martha, 15, Mattie Crenshaw, 18, and Hurt Hamilton, 20, field hand. Could Martha and Mattie be step-daughters?
Some say Adam died in Kerr Co, TX and was buried in Waelder, Gonzales Co, TX.
