Additional Records with Birth Information
Substitute records can contain information about more than one event, and are used when records for an event are not available. Because the substitute records may not be created at the time of the event, it may contain incorrect information. Search for as many substitute records as possible to corroborate information found in substitute records to help improve accuracy.

Tips for finding births
Successfully finding birth records in online databases depends on a few key points. Try the following search suggestions:
 * Spelling variations. Your ancestor's name may be misspelled. Search with spelling variations for the first and last name of your ancestor.
 * Search parents. Search for the parents, if known, as the child's first name may not be on the birth record.
 * Search given name. Search by given name (leave out the last name) with the approximate date of birth.
 * Add information. For common names, add more information to narrow the search such as approximate birth date or parent's names if known.
 * Date range. Expand the date range of the search by 5 years.
 * Search state. Search using the state name only instead of by county.
