This appears to be her as her March 9th 1865 affidavit to the Provost Marshall states she is 20 years old and a native of Livingston Co.
In her statement she states she married James Rider/Ryder Oct 2 1860 in Livingston Co Mo. Looking at the marriage records of Livingston Co Mo 1837-1863 I find lo and behold a record of a marriage of James Ryder to a Loretha Winkler on Oct 2nd 1860 officiated by Nathaniel Watson J.P.
