Daniel Radcliffe is moved to tears as he explores his family history in an upcoming episode of BBC's "Who Do You Think You Are?"

The Sun reported that at some point during the nearly hour-long episode, Radcliffe breaks down while reading his great-grandfather Samuel Gershon's suicide note. 

“Everything he had worked for and that his father had worked for, has sort of been destroyed," the actor reportedly says. “You want to just reach into the past and just go ‘whatever you’re going through, you have so much to offer the people who are around you still... you have so much to give to them. And, they still would all have loved you.'”

The 29-year-old learned of the events that lead to his great-grandfather taking his own life while on the British show. Apparently, in 1936, Gershon filed a claim after his jewelry store was robbed only to be accused of faking the incident in order to claim the insurance money. Unable to face the "bankruptcy and failure," as People described, Gershon died by suicide at 42 years old. 

A police report seemed to suggest that Radcliffe's great-grandfather was likely denied payment at first due to the anti-Semitic climate that existed at the time. “Jews are so frequently responsible for the bringing down of their own business premises,” the statement evidently read. 

The apparent prejudice of police comes as a shock to the "Harry Potter" star, who is of Russian and German descent. “There’s a lot to dig into in that one sentence," he says. "It’s very jarring to see being a Jew to be taken as a piece of evidence in itself.” 

Radcliffe's episode of  "Who Do You Think You Are?" premieres on July 22.
