A feud has erupted within the first family of reggae, with the widow and nine children of Bob Marley suing his half brother to stop use of the Marley name to promote an annual Miami music festival and profit from other businesses in his native Jamaica.

The lawsuit filed Thursday in federal court contends the half brother, businessman Richard Booker, and several affiliated companies are violating copyright and trademark laws by using Marley’s name, photographs, lyrics, symbols and other intellectual property without authorization.

The lawsuit says people could be deceived into thinking those uses are officially endorsed by Marley’s widow, Rita Marley, and their children. Booker and Bob Marley shared the same mother.
