Additional Records with Birth Information
Substitute records may contain information about more than one event and are used when records for an event are not available. Records that are used to substitute for birth events may not have been created at the time of the birth. The accuracy of the record is contingent upon when the information was recorded. Search for information in multiple substitute records to confirm the accuracy of these records.

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.

Known Record Gaps
Records Start
 * 1877 County clerks required to record births. However, compliance to the new law is not enforced and the registration is incomplete in most counties.
 * 1916 Statewide Registration.

Records Published by FamilySearch Collection coverage tables show the places and time periods of original records published by FamilySearch. For any FamilySearch collections you did not find your ancestor in, check the coverage table for gaps in the online collection. If the time period or location your ancestor lived in is missing from the collection, it may require searches in records found at original repository or finding substitute records for the event.
