The Boston Evening News was published from 1830 to 1941. Between 1906 and 1941, it featured a genealogy column in which readers would submit and respond to queries. It is estimated that two million names had been included in those columns. This collection is part of the archives at the New England Historical and Genealogical Society.
Recently they partnered with FamilySearch to digitize the collection. Several weeks later the scanning was completed and the collection is now browsable at AmericanAncestors.org (the NEHGS website). The Vita Brevis blog has details on the collection and tips for using it to learn more about your family.
