Description:
From October 1831 through October 1921, the Boston Pilot newspaper printed a “Missing Friends†column with advertisements from people looking for “lost†friends and relatives who had emigrated from Ireland to the United States. This extraordinary collection of 39,039 records is available here as a searchable online database, which contains a text record for each ad that appeared in the Pilot.
