Leah, I saw your inquiry re: John Wesley Gately. John was married to my great aunt, Nancy Cordelia Hill. After doing some searching, I found John living with the Robert Plunkett family in Sangamon Co, Cartwright Twp. He was a farm laborer and born in KY. On the 1880 census,John and Nancy were living in the same twp, next to Nancy's brother, Richard. John, his mother & his father were all born in TN, so it says.
Regarding information you have on Nancy is not completely correct.There is another Nancy Cordelia Hill in 1850 in IL, but my family is in TN and didn't come to IL until the early 1850s.Nancy was born in 1850, the last of nine children at that time.Her mother was born in TN, and her father was born in NC.
If you would like to contact me, I would be glad to share my info.
