In the 18th and 19th centuries, newspapers-- especially big-city newspapers-- carried ads from the local post office, listing area residents that had letters in need of retrieval. While the ads don't offer any solid genealogical information, the fact that someone was believed to be living in a certain place at a certain time may be helpful in tracking down more meaningful records.
