Your question made me look deeper. The service record card says "died at cantonment Washington Ark." Since everyone in north and central Texas who had arrived in Texas since the early 1830's had come by way of what became known as Washington (town), that was what we have always assumed was intended by the entry. However, his company's November December 1861 muster was at Fort Gibson, some 75 miles west of Fayetteville (in Washington County). The entry also does not say why he died, so we are making an assumption that is perhaps false -- perhaps an accident?
So thank you for making me re-look at the information.
