The old county histories are full of individual biographies. Most of the counties of the U.S. have had at least one county history written. Sent out by the proud new parents to friends and relatives. The one thing you can count on is the date and place of birth of the person. Filed first in a county or town, then a state copy filed.
Deceased persons transported across state lines usually require a burial permit.
Filed at a county or state health department, data about the deceased, including a date and place of birth may be included. Found at a city or county office. Modern records have great genealogical information. Earlier ones may only give name and residence. Many churches maintain christening records, which in most cases are naming ceremonies.
