I'm often struck how published US obits changed during 20th century (along with regions). Late 1800s obits were formal. They included family members and church affiliations. Cities were small industry/mercantile areas, surrounded by working farms. A few ethnicities dominated, depending on the industry and location. Local directories listed street names/landmarks, noted their death or the city they 'removed to'. 1920s obits came with more details about the decedent's lives and families. Church affiliation was inferred by funeral arrangements. Cities were larger; ethnicities clustered in neighborhoods. Local directories listed home & work name/addy, the wife's name or the spouse's name of a widow. From 1940s to 1970s, obits became longer and included extended family, marriage dates and accomplishments (inc church). Military history became prominent in the 60s and 70s. Major cities were huge and adjacent areas were distinct places. Ethnicities were more spread out. Phone books had numbers and addresses. In the 1980s, obit length tended to shorten to minimal details but could be longer if the decedent knew a lot of people. Families were often spread out. Cremations replaced burials.
