Aside from names that are spelled wrong, first names that are omitted, and names that are flat-out wrong, there are at least two other big reasons you may have difficulty finding a newspaper entry for your relative simply by querying a database:
- the database of newspapers may be incomplete and
- the original images are virtually impossible for OCR (optical character recognition) to recognize.
Browse the images to determine if there are gaps in the newspapers online at the site and look at some images from the time period in question to determine how legible. Some digital images of newspapers were made in the early days of microfilming and may be difficult for the computer to interpret.
You may have to read them manually and search them that way as well.
