If you are uncertain of the spelling, you may enter a partial name ("kerck%"), and the lookup will return any names containing those letters in that order.
Refining your search: If you are searching on a common name, such as Lewis, be sure to omit the "%" at the beginning of the name ("lewis%"), s o the lookup will return only voters whose last name is Lewis. Also, you can inc lude the first initial or as much of the first name as you know. Be sure to incl ude a space between last and first names ("lewis ann%").
The % is the wild-card character. It is required for most lookups.
