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
Success with finding birth records in online databases depends on a few key points:
 * Your ancestor's name may misspelled. Try the following search tactics:
 * Try searching for the parents if known. Sometimes a child's first name is not on the birth record.
 * Try different spelling variations of the first and last name of your ancestor.
 * Try a given name search (leave out the last names)


 * Expand the date range of the search.
 * Try searching with the state name only instead of by county.
 * If your ancestor's name is common, try adding more information to narrow the search.
