This does not mean that her husband was dead! If you do not have a death record for a "deceased" spouse, look for the person in the census anyway. (Clara had three more years until Herman died.)
|Marital Status: Clara was divorced, not widowed.|
Howard was married, but separated from his wife.
Lillian was single, but married John Kuhl two months later.
In this case, I knew that Clara Uhl and Herman Lutter divorced in the 1890s and Herman died in 1923. In the 1920 census, Herman resided nearby with his next wife, Emma Neubauer.
