One of my great-great grandmothers was Margaret (or Margarette) McDivitt, born 3 Jun 1831, married James Tosh Acton on 27 Apr 1848 in Ashland, Wapello, IA. She moved to Kansas with JT, settling in Nelson Township, Cloud County. She died 16 Oct 1909 and is buried there. Her father was Charles McDivitt, born 22 Mar 1799, died 23 Apr 1868. Her mother was named Fannie, born 23 Mar 1801, died 13 Aug 1864,but that is all I know of her. Most of the above dates are hearsay, but may help to establish whether we are talking about the same McDivitts.
Since your marriage date is plausible and the names fit, do we have a match?
