EL PASO, Texas -- A Texas judge has ordered DNA testing on a man who claims to be the brother of the late "The Jeffersons" star Sherman Hemsley.

Richard Thornton is challenging the validity of Hemsley's will, which names the actor's longtime manager, Flora Enchinton of El Paso, as sole beneficiary. Hemsley died of lung cancer July 24.

Judge Patricia Chew on Monday rescheduled the El Paso trial on Hemsley's estate to begin Oct. 31.

Thornton, of Philadelphia, sought the DNA testing and must provide results by Oct. 15. Hemsley was born in Philadelphia but had lived in El Paso for the past 20 years.

Court documents indicate Hemsley's estate is worth more than $50,000.
