Individuals sometimes placed an advertisement regarding a "missing" relative in the The Boston "Pilot" newspaper in the 1800s in the hope of tracing members of their family who had emigrated from Ireland to America and Canada. These are valuable to researchers in that while names of townlands may be misspelled they can be of help in tracing an immigrant's journey and identifying other relatives:
In January of 1855, Hugh O'Rourke, formerly of Lattoon, near Kiltyclogher and Garrison, Co. Leitrim, was being searched for by his nephew, Jno. O'Rourke, St. Johnsbury Plain, Caledonia Co., Vermont. The last contact the family had was in the form of a letter written to his sister, Margaret, of Leeds, Canada East, sent from Cobergo, CW (Canada West?).
Mathew Magovern of Tully, Carrigallen parish, had immigrated to America circa 1846. When last heard from he was in the eastern part of Ohio in Muskingum Co., where two uncles by the name of Walpole were thought to have lived. Nine years later, his brother, James, placed an ad requesting information in which he mentioned that he, also, had recently emigrated. Replies were to be sent to Charles Keirnan of Old Cambridge, Massachusetts.
