Thanks, Mike.
My 4G grandparents Garrett Bonham (1813-1870) and Julia Ann Claywell (1823-1911) and their children traveled by wagon from Macomb, Illinois ~1859 and settled in [S]cyene, outside of Dallas, where they appear in the 1860 Census (household of Garret Bonham). Garrett Bonham also appears in the 1861, 1862 and 1864 Dallas County tax rolls. They headed back to Illinois about a year after the war ended, and ended up settling in Neosho county Kansas before 1870.
Most of this information came from typed transcripts/memoirs that have been photocopied several times and passed around the family. I'm trying to track down the originals and get permission to redistribute them (with better information about when/why they were created). They are fascinating accounts of "pioneer life." I especially like lengthy account of my 3G grandmother, who was about five-years-old when the family started their journey to Texas, and she either wrote out or dictated her recollections when she was an adult, with information about the wagon in which they traveled and how they learned to make thread and weave fabric when they couldn't buy new fabric in Texas during the war.
I didn't see any Bonhams from Texas in WeRelate that looked like close relations, but do think they have common ancestors several generations before. What a treasure trove of information you've assembled! I enjoyed looking through it.
