1950 Census Oddity- FS Index & Ancestry Index Of Same Census Sheet Contradict
Please refer to Thelma Ann Butler (LVP2-2VC) Research Help for 1950 Census. Thelma's Marital Status has been indexed in error as Widowed. Review of the image finds her as Wife/Married. https://www.familysearch.org/ark:/61903/3:1:3QHK-9QH7-TJG5
A review of the same Census sheet in Ancestry finds her correctly indexed as Wife/Married. https://www.ancestry.com/imageviewer/collections/62308/images/43290879-Oregon-103941-0002
How is this possible? Why don't the indexes match? I thought FS and Ancestry collaborated on indexing the 1950 Census. Did the Artificial Intelligence at Ancestry get it right, and the human review at FS err?
Also frustrating is in FS only 4 fields of the 1950 Census index can be edited, yet in Ancestry 19 fields can be edited.
