More than eight decades after the fall of the Third Reich, uncovering family ties to the Nazi regime has become easier than ever. Through the US National Archives, individuals can now freely browse millions of digitized index cards online to discover if their grandparents or great-grandparents were members of Adolf Hitler's NSDAP.
This massive digital database spans over 5,000 microfilm rolls and contains the records of roughly 6.6 million Germans who joined the National Socialist German Workers' Party prior to 1945. However, the archive is not exhaustive. According to the German Historical Museum, by 1945, one in five adult Germans—totaling 8.5 million people—held party membership, thereby supporting the oppressive regime at least on paper.
While the US database offers unrestricted online access, tracing Nazi roots within Germany remains bureaucratically complex. Historian Johannes Spohr points out that while the online search is highly appealing to the public, similar records have been available at the German Federal Archives since 1994. "And there you actually get a lot more information than just these memberships," Spohr notes.
The disparity lies in Germany's strict privacy regulations. Information is typically restricted until 100 years after a person's birth or ten years following their death. Furthermore, these records are not digitized for public browsing; they require a formal written application. Unlike the US system, German law dictates that private individuals can only request files pertaining to their direct relatives. "To this day, the persecuted, the victims, are much more public, complete with names and identities. When it comes to the perpetrators, things are still quite vague," Spohr explains.
For roughly 11 years, Spohr has operated "present past," a research service dedicated to helping people investigate their families' Nazi-era histories. His clients span all age groups, ranging from 20 to 90 years old.
"We are currently at the transition between communicative and cultural memory, where things can only rarely be passed down orally, and where people can be questioned less frequently," Spohr observes. As eyewitnesses pass away, archival research replaces personal interaction. Today, even the fourth generation is actively investigating ancestors they never personally knew.
Despite Germany's internationally praised culture of remembrance, personal family histories are often sanitized. A recent study revealed that more than two-thirds of Germans believe their ancestors were not Nazi perpetrators. Nearly 36 percent consider their relatives to have been victims, while over 30 percent believe their forebears actively helped potential victims, such as hiding Jewish people.
Spohr dismisses these sanitized narratives, stating, "These answers stem partly more from feelings than concrete knowledge." He notes that families rarely discussed their actual roles after the war. "Memory must also take place where it hurts," he emphasizes, adding that today's generations are largely dealing with post-war myths and defensive mechanisms designed to deflect guilt.
While the digitized index cards provide essential data—such as names, dates and places of birth, entry dates, membership numbers, and occasionally addresses or portraits—they lack historical context. They cannot indicate whether an individual was a staunch fanatic, a mere opportunist, or a passive follower.
Furthermore, because only about 80 percent of the original index cards survived the war, an ancestor's absence from the database does not definitively prove they were not a committed Nazi. As Spohr notes, discovering a membership card is just the beginning of the actual research, as party membership alone does not paint the full picture of an individual's historical guilt or innocence.
