Genealogists expect to type names in boxes and have the desired results appear, especially with census records. If you have a good idea where the ancestor lived and cannot find him in the index, read the census manually. For rural areas and small towns, it is not all that difficult and, if you have an address in urban areas it is possible there as well. This can be a great way to find people whose names are jumbled and, in the process, find nearby relatives for whom you never thought to look.
