There is no information about Margaret’s life in the intervening years until the 1930 census was taken. It showed Margaret as the head of her household. She owned her home, valued at $4,000. It was located at 445 Main Street, Pomona, California. Newer buildings have replaced the homes in Margaret’s neighborhood since then.
Living with Margaret was her widowed daughter, Harriet Carr DeYoe, and Margaret’s grandson, Paul Palmer DeYoe. Paul was adopted by Harriet and her husband, Willard, after Paul’s mother, Nellie Carr Palmer, died in 1919.
Other information on the census form stated that the family had not yet purchased a radio set. Radio broadcasting was still in its infancy. The National Broadcasting Company (NBC) began in 1926; followed by the Columbia Broadcasting System (CBS) in 1927.  Evidently, the government wanted to know how many people could receive radio news broadcasts as of 1930.
Margaret was 82 years old, Harriet was 51 years old, and Paul was 20 years old. None in the household worked. Paul was attending college, so they must have had sufficient resources to live on and provide Paul with a college education.
