A birth record contains information about the birth of an individual. On a birth record, you can usually find the mother's full maiden name and the father's full name, the name of the baby, the date of the birth, and county where the birth took place. Many birth records include other information, such as the birthplaces of the baby's parents, the addresses of the parents, the number of children that the parents have, and the race of the parents, and the parents occupations.
