My GGG Grandfather Joel Shelton purchased two land grants in 1826, one in 1830. David his son purchased one in 1834. All are in Township 14-N. This isn't far from present day Arlington. The name of Arlington in those days was Burlington. I have a Atlas of Rush County. Arlington is in Posey Twp. Joel is listed as a pioneer of that township. I see that William Riddle also purchased land in Montgomery & Hendricks County. It may be that he purchased the land in Rush County, but never lived there.
