Jackie Guthrie, the wife of legendary folk singer Arlo Guthrie, died on Sunday at the couple’s home in Sebastian, Fla., after losing her battle with cancer. She was 68.

An obituary released by Guthrie's record label says Jackie Guthrie had inoperable cancer.

In a Facebook posting, Guthrie describes his relationship with his wife as  "a very great love."

"We didn't always like each other," Guthrie wrote. "From time to time there were moments when we'd have our bags packed by the door. But, there was this great love that we shared from the moment we met -- a recognition -- It's YOU! And we would always return to it year after year, decade after decade and I believe life after lifetime."

Having grown up in Malibu, Calif., Jackie Guthrie met her future husband in 1968 while working as a cashier at the Troubadour, the Hollywood nightclub that was an epicenter for folk music at the time.

The next year, the couple bought a 250-acre property called “The Farm” that the family still owns in Washington, in western Massachusetts. They were married on the front lawn in October of that year.

The couple raised four children, and in recent years the family toured together, with Jackie working as the videographer.

This past summer, during a tour to mark the centennial birthday of Woody Guthrie, Jackie reportedly became so weak she could barely hold up the camera. In early September, she was diagnosed with inoperable liver cancer.

Guthrie has postponed several upcoming shows but promises to reschedule them as soon as possible.

Jackie is survived by five children and 10 grandchildren.
