Many families have stories about the criminal behavior of one of their family members. It’s natural to not want to talk about or explore these events because they can make us feel embarrassed or even ashamed. But, you don’t have to commit murder or make counterfeit money to be considered a criminal. Something as simple as littering can result in a fine and a person’s name being entered into the criminal record books for all eternity.
Even if you don’t know if anyone in your family committed a crime, exploring this path of research may yield important clues to your family history.
While the words “criminal records” implies that someone was convicted of a crime, this is not always true. Your grandma Daisy may have been arrested during Prohibition on suspicion of making moonshine. She was fingerprinted, mug shots taken, she pled not guilty (because, of course, grandma Daisy would never do such a thing) and she was put on trial. Even if the court found her innocent or the charges were dismissed on a technicality, her “criminal records” still exist.
For this reason, searching for criminal records can be a smart next step when your genealogy research has hit a dead end.
Criminal records are extremely valuable for genealogical research as they are more detailed than many other types of ancestral records and can contain photos, address information, physical descriptions, and details on distinguishing marks.
For example, distinguishing marks like a relative with a tattoo or missing limb or eye might indicate that they served in the military. Imagine finding an old mug shot of a relative who is wearing a fraternal or other organizational pin on the lapel of their jacket. An entirely new avenue of exploration opens up.
Where to Find Free Sources of Criminal Records for Your Research
There are a vast array of resources on the internet for finding criminal records, especially at the state level, but when you first dive into searching you might feel overwhelmed. The following information will give you a basic understanding of what kind of criminal records are available and where you can find them online for free.

There are four main types of court records in the US: dockets, minutes, orders and case files.
Dockets are the calendars of the court. They show the names of the plaintiff and defendant, the case file number, the date the case was/will be heard, and all the documents related to the case. Normally, dockets are in chronological order by date and you will find some that are indexed for searching.
Court clerks keep the minutes of all the actions taken by the court. These include a brief description of the actions the court took and the names of the defendant and plaintiff. Like court records, minutes are in chronological order, but they are rarely indexed.
Orders are the judgments made by the courts. They consist of a brief description of the case and explain what the court decided. These records are helpful in many aspects of genealogy research besides investigating a person’s criminal history. Court orders may contain very unique pieces of information like the appointment of guardians, orders granting citizenship, and the re-recording of deeds in cases where land records were destroyed. You won’t find this information in any other court records.
Case files often contain the most helpful genealogical information. Legal cases always have a case number (found on the docket and other records) and this is an important piece of information to have if you can find it, because case files may contain detailed testimony, evidence, depositions, petitions, and correspondence vital to your research.

Prison and Jail Records
One important aspect to understand about this type of criminal record is the difference between prisons and jails. People often get the terms mixed up or use them interchangeably. Jails are normally run by local authorities and are for holding people awaiting trial or who are only serving a short sentence, likely due to a misdemeanor conviction. Conversely, states and federal governments normally run prisons which are reserved for those with felony convictions are serving longer sentences.
The US Bureau of Prisons has records of inmates from 1982 to the present day. On the webpage, you can search by name (a first name is required), race, age, and sex. The results give you their registration number and show if they have been released and when.

Some people start out in the prison system early in life, so checking the records of reformatories may prove valuable in your search for a relative and their life history.
For example, Colorado has a free, searchable online database of reformatory records from 1887 to 1939. While searching is free, fees are required to get copies of information from the archives when you make a request. The information in the files includes mug shots, prisoner records, and parole records.

For records up to 1870, you can request information on the date the prisoner came to the penitentiary, their discharge date, and their state of birth.
Mug Shots of Your Criminal Ancestors
These photographic records used in crime investigations were created by a French criminologist named Alphonse Bertillon in the late 1800s.
Mug shots are usually found accompanied by other helpful genealogical information such as physical descriptions, aliases, location information, and details about any convictions. Knowing what crimes your relative was convicted of may give you clues to what other records may be available. Also, if you’re into people watching or just enjoy history in general, these records make very entertaining reading.
