Adoption and guardianship records

Old adoptions and guardianships were decided by local courts, usually the county probate court; guardianship files are often open, but adoption files can stay sealed for decades.

For most of American history, a child who lost a parent was not adopted in the modern sense. A court appointed a guardian to look after the child and the child's property. Massachusetts passed the first modern adoption law in 1851, and Ohio's first adoption statute followed in 1859, so formal adoption records begin at different dates in different states.

Both kinds of case were handled by local courts, and both can name a child's parents, guardians, and new family. The difference for a genealogist is access. Adoption files may be closed by state law even when they are very old. In Utah's state archives, for example, a county probate index of estates, guardianships, and adoptions is open to the public, while the adoption records it points to are sealed. The index can still tell you that a case exists.

Guardianship came first

Ohio's history shows the pattern. In the Northwest Territory, orphans' courts set up in 1795 supervised the guardians who managed the property of orphans and minor children. From 1803 to 1851 the county Courts of Common Pleas appointed guardians and watched over their accounts, including land. If the father died or could not care for the child, the court appointed a legal guardian, and the mother was not considered the legal guardian. From 1851 the new probate courts took over guardianships of minors and the review of guardians' accounts.

Read those rules into the record. In early Ohio, a guardian appointed after a father's death does not mean the mother had died too, since she was not considered the legal guardian. The Ohio History Connection is also clear that guardianship did not make a legal adoption.

The first adoption laws

The Massachusetts Adoption of Children Act of 1851 directed judges to make sure an adoption decree was fit and proper, and left how to decide that to the judge. Ohio's first adoption statute became law on March 29, 1859. Any unmarried inhabitant, or a husband and wife together, could ask the county probate court to adopt a minor child not their own by birth and to change the child's name. An 1870 amendment allowed institutions to place children with adoptive families.

Because the same petition could ask for a new name, an Ohio adoption record can link a child's birth name to the adoptive name. In Ohio, adoption case files from 1859 on are at the county probate court where the adoption took place, and the court's journals, order books, and complete records are among the best places to find the proceeding. The Ohio State Archives holds some county volumes, such as a Franklin County adoption complete record covering 1852 to 1955.

When adoption files were closed

Early adoption records were not secret. Historian Ellen Herman's Adoption History Project at the University of Oregon notes that the adoption records of early twentieth century courts and agencies were open to anyone curious enough to look. In 1917 Minnesota revised its law to make adoption records confidential, and between the world wars most states followed. Confidential then meant closed to the public but still open to the people directly involved.

When courts issued adoption decrees, states also began to produce new birth certificates naming the adoptive parents and to seal the originals, which named the birth mother and sometimes the father. According to the project, secrecy that shut out even adult adoptees came only after World War II; until 1945 most members of adoptive families had legal access to birth certificates and adoption court papers. Some states still close old files for a long time. In Utah, adoption records are sealed for 100 years and released only by court order.

What you can ask for today

The rules are state law and change often. Child Welfare Information Gateway's summary, current through December 2019, separates two kinds of information. Nonidentifying information covers things like the date and place of birth, the birth parents' ages, descriptions, health, education, and occupations, and the reason for the placement. Nearly all states let an adult adoptee ask for it in writing, usually from age 18.

Identifying information, such as names and addresses, is usually released only with the consent of the person it describes, or by court order for good cause. About 30 states had a mutual consent registry, some used a confidential intermediary to contact birth relatives, and about 37 let birth siblings exchange identifying information by mutual consent. In about 19 states, as of 2019, an adoptee still needed a court order to see the original birth certificate. These laws name who may ask, so check your state's current statute to see whether a descendant qualifies.

Other records of a child's new home

Children who were not adopted may appear in the records of the places that cared for them. In Ohio, county children's homes, authorized in 1866, kept their own admission, discharge, and death records, which passed to the county commissioners when a home closed. Orphaned children, or children whose parents could not care for them, also lived in county infirmaries.

Under Ohio law today, probate courts must send birth, medical, and putative parent information from adoptions to the state Department of Health, which keeps a statewide file naming adoptees and their adoptive and birth parents. For later Ohio adoptions, the Ohio History Connection advises contacting both the county court and the health department.

On the page, look for

Write down the child's names before and after the change, and the years when the change seems to happen.
Look for the father's death, or a sign that he could not care for the child, which in early Ohio led a court to appoint a guardian.
Search the county court index for guardianship and adoption cases under both the child's and the adults' surnames.
Read the guardian's appointment and accounts for the names of the child, the dead parent, and any property.
In an adoption entry, note the petitioners, the child's former name, and the new name.
If the file is sealed, ask whether an index entry, a docket line, or a court order can be released.
Check the state's current access law before asking for an original birth certificate or registry search.
Look for children's home and county home records if the child spent time in care.

Where to see them for free

The probate court, or the court that handled estates and guardianships at the time, in the county where the child lived. Ask for the index, the journals or order books, and the case file.
The state archives, which may hold older county court volumes and indexes. Utah's Rich County probate case index, for example, is online and gives the parties, the type of case, and the case number.
The state vital records office or adoption registry for original birth certificates and registry services.
Child Welfare Information Gateway's State Statutes Search for a summary of each state's access law.
