Why is Halloween pumpkin called Jack? Is there any source?

Halloween pumpkin is called Jack because of Irish legend. In Ireland, a man named Jack was invited by the devil to drink. After drinking, Jack found that he had no money to pay the bill. Jack persuaded the devil to turn it into sixpence to pay for the wine. But instead of paying, Jack used a silver note to stop the devil from coming out.

Then the devil promised Jack that he wouldn't scare him for a year, and then Jack let the devil out. However, on Halloween the following year, the devil appeared again, but the devil promised not to harass Jack for a year, but Jack died in an accident before the year was completely spent. After Jack's death, heaven didn't take him in because Jack was very stingy and inhuman, but hell didn't want to take him in because he had teased the devil.

Later, Jack had nowhere to go. Finally, he had to wander around the world constantly, carrying white radish, but there was charcoal fire that the devil lit his way. Jack found a place to rest. Later, Irish people made lanterns with potatoes or kohlrabi. /kloc-In the 1940s, new immigrants came to the United States, and they found that one material was better than white radish, that is pumpkin, so the pumpkin lanterns we see today are usually made of pumpkin.
