Earlier in the month I posted a photo of the headstone of Thomas Robert Jones and Sarah Ellen Armstrong in Montgomery County, Indiana. I am now catching up with more information on my 2nd-great-grandmother, Sarah Ellen Armstrong. She was the daughter of David Armstrong and Easter Vail, and was born on 7 December 1868 in Jefferson Township in Boone County, Indiana.
In the 1870 US Census, the family appears as:
In 1900, the Jones family lived in Jefferson Township, Boone County, Indiana in the household of Sarah's mother, Easter Vail Armstrong.
Update - 3 April 2012 - First Find in the 1940 Census
