I found Marguerite L. Hunter soon after the release of the 1940 US Census on April 1, because I knew she was in Hampton Township, Allegheny County, Pennsylvania, so I didn't need the index to find her.
|1940 U.S. Census, Hampton, Allegheny, Pennsylvania, Roll T627_3404, E.D. 2-209,|
page 12B, lines 49-52, household of Marguerite L. Hunter.
Living on Route 8 (no house number), Marguerite L. Hunter is the 63-year-old widowed head of household. Living with her are daughters Margaret (age 34 and single) and Mary Gerkan (age 36 and divorced) and a servant, Anna Zoeller. Five years before, Marguerite and Margaret lived in the same house and Mary lived in Pittsburgh. (That marriage and divorce is another story.)
Marguerite owns the house, it is valued at $25,000, and No, it is not a farm (although my mother always referred to the home as her grandmother's farm). [January 4, 2014 update: My mother re-read this post and told me that the "farm" was separate from this house, a couple of miles down the road. There was a tenant farmer who raised chickens and pigs and grew vegetables and hay.]

Before great-grandfather Percy Hunter died in 1937, sometime between 1930 and 1935, Percy and Marguerite built their "house in the country" in Hampton Township, shown below, which my mother fondly remembers from her childhood. (See the 1930 census record of Percy and Marguerite still living in Pittsburgh.)

My mother's grandmother died in 1967 at age 91, so I will be looking for her in the 1950 and 1960 US Censuses.
