Currently covering 1911 to 1941 (the column ran from 1906 to 1941) the collection is browsable only not searchable. The tip is to use the American Genealogical-Biographical Index (AGBI) on Ancestry.com as a search aid to find the newspaper year/month/date that an ancestral surname (ancestor) appeared. Also many issue from the 1850s to 1910s are on Google News Archive.
The genealogy column consisted of queries from across the country dealing with ancestral questions regarding ancestors in many places and time periods -- not just New England. These queries were answered by readers and others too.
