From The Seattle Times:

Not long before his death, Al Hendrix seemed willing to keep his second son out of the Hendrix family business at his adopted stepdaughter's request, according to a Hendrix family matriarch who testified yesterday in the civil trial over the estate of rock legend Jimi Hendrix. But, he never intended to cut Leon Hendrix out of his will, said Delores Hamm, the maternal aunt of Leon and Jimi Hendrix. Hamm said she had remained close to Al Hendrix even after his divorce from her sister. On the stand yesterday, Hamm recalled visiting Al Hendrix in the hospital not long before his death in 2002.

Diana Carpenter, who lived with Jimi Hendrix in New York City and claims to have had a daughter with him, told a reporter at the trial the legal conflict would have made Hendrix sad.

"It's a shame," she said. "He was a sweet-hearted man, and not greedy. Not greedy at all."

From Seattle Weekly:

But then there are Hendrix's unacknowledged "love children," Tamika Laurice James-Hendrix and James Sundquist (a Swedish national who changed his name to Jimi Hendrix Jr.), who also are not sharing in Jimi's legacy. Tamika was born in 1966, after Jimi's brief relationship with Diana Carpenter. Hendrix was notified about her in 1970, but never took a blood test to prove paternity. James was born in 1969 after an affair with a Swedish fan. A Swedish court recognized Sundquist as the guitarist's son, but he has never been recognized as such in the United States.
