At your link, Alabama and Texas and Virginia all use some form of the word “slaveholding.”
Also, they all use the word “Ordinance.”
So, I'm not completely sure what your point was.
By the way - two of my great-great grandfathers were wounded at Pea Ridge. They were German farmers from northern Illinois - and possibly exchanging fire with some of your ancestors?
"The ordinances of secession were the actual legal language by which the seceded states severed their connection with the Federal Union. The declarations of causes, given elsewhere on this Web site, are where they tended to disclose their reasons for doing so, although only four states issued separate declarations of causes."
