*** so spelling of her name is wrong, but that is not unusual for census records husband John is alive in 1851 but I have not foundhis death
I went back to look again at the birth/baptism for John Churchfield and when I look very closely at the names of his parents it looks more like John Churchfield and Judas Etanton or Etanston or Etanteau than Stanton ?? actually hard to tell BUT her burial does look like Stanton to me.
I just found the baptism for Celia Churchfield, sister to yourJohn
It says baptized June 17, 1832, daughter of John Churchfield and Judea Steanton. Sponsors Thomas Lane and Rose Nelo.
