I tend to skip the record summary on most hits from census searches and go directly to the image. This can be a mistake.
The record summary for Ira Sargent in the 1836-1925 Iowa State Census Collection indicates he is living in Davis County, Iowa, in 1856. Other members of the household are also listed on the record summary page. I rarely click on these names, preferring to read the actual image whenever possible. When re-reading the record recently, I clicked on each name in the household, pulling up those record summaries just to see what they said. I was glad I did. One of the other names in the household (Edwin Sandon) was difficult to read and another Ancestry.com user had entered in an alternate reading of the name, which only appeared on his record summary. Fortunately, I was able to send the person who made the correction a message by clicking on the “Contact this person” link on the corrections page.
Had I not viewed the record summaries for the others in the household I would have missed this possible connection.
