Amariah Swanner was reportedly part of a 40 some-odd wagon train that departed Alabama in 1867. The Swanners were living in Butler Co, AL at the time of the 1860 US Federal Census. The wagons were reportedly abandoned in Louisiana due to flooding and some members of the party made their way to Galveston by boat. Amariah registered his cattle brand in Coryell County in 1870. He settled on land bordering Cowhouse Creek about 14.5 miles southeast of Gatesville. The Swanners were in Stephens County, Texas by 1880.
I have not been able to locate the family in the 1870 census. Searching for information on the Wagon Train/Boat travel to Texas.
