He didn't really move around a lot. You're looking at several different George Thornburgs. There were many with that name born in Indiana and Illinois between 1845 and 1855. Our George was born approx 1847 ( my family records show Aug 1847, Clark County, Illinois); one or two records show him born in Indiana, but, his military records, etc. all show him born in Illinois. He was in the Civil War, which moved him a bit; then, married Nettie in Illinois. They lived in Texas for a brief period and then went to Pontotoc, Oklahoma where he stayed until after she had passed away. He remarried at 63 yrs of age in Nov 1910, in Pontotoc County, Oklahoma. After that, we can't find any record of him or his new wife.
