Jackson, Miss. John Hampton Stennis, the only son of late U.S. Sen. John C. Stennis, has died at 78.
Kim Perrett, a spokeswoman for the Jones Walker law firm, confirmed Stennis died Thursday morning.
Stennis was a partner in a law firm, Watkins, Ludlam, Winter & Stennis, that merged with Jones Walker in 2011.
Besides his legal career, Stennis served in the state House of Representatives from 1969 to 1984. He lost a congressional race in 1978 to Republican John Hinson.
Stennis was born in the Kemper County seat of DeKalb, his father's hometown, but mostly lived in Jackson. He rose to be a brigadier general in the Mississippi National Guard.
His father served 41 years in the U.S. Senate, dying in 1995.
