I can only use Ancestry at the library itself, and won't be able to go for a couple of weeks. But the IL Trails site was a help, even tho I didn't find Bastion there. I DID find John and Hannah Seas in the Coles Co. 1850 Census. It's an unusual name. An Aaron Seass, a younger generation, married Bastion's eldest daughter in 1873. I believe I have John and Hannah's burial in the Seass cemetery in Moultrie Co. So you helped me find one more little piece of the puzzle. And all the little pieces help. The short history of Coles Co. and Mattoon, where Bastion's son was b. in 1859, was also a small piece of the puzzle. I hadn't thought of Cumberland Co., so will try the same sources there. So thank you!
