Soundex searches usually do not find spelling variants that begin with a different letter than the name for which you are searching. A soundex search for Cain will normally bring up Cane, Caine, Cone, etc. but will not locate Kain, Kane, Kaine, etc.

When working on a new name list all the variants of that name and remember that Soundex searches only bring up results with the same initial letter of the name entered.

A Soundex search for Night won’t usually locate Knight either.
