Been following this thread. It's been awhile , but I believe there was a Gilliam or Gilliam City in Saline Co as I had some Thomas relatives that lived there at one time and also at Orearville in Saline. I would guess both towns where named after both their families in this post. However I believe both of these towns were in the North Central and North East part of the County, aways from Grand pass.
