Looking for John S. COULTER, b. 1822 who married Margaret McKELVY, b. 1822 in Randolph County, IL on February 10, 1842.
Have found them on the 1870 Census of Washington County, IL "Pilot Knob" page 15, lines12-19. Cannot found them on the 1880 Census for IL. There is a John COULTER listed on the Kansas Census at age of 70, b. KY, wife Margrett, age 48, b. IL-show 5 children. Names are not what I have. Also found a John W. COULTER listed on the IL Census for White County, age 51, b. IL, wife Margaret, age 50, b.IL. Have 3 children listed. Names are not what I have.

Would appreciate any help on this family.
