Yes, Regulus Arcturus Black was a Death Eater. He discovered Voldemort's Horcruxes after Voldemort borrowed Kreacher, his house elf, to hide one of them.
Harry and Dumbledore find the locket Horcrux, which is the one Kreacher helped hide, and discover it is a fake. Inside is a note left by R.A.B who planned to destroy the Horcrux.
Regulus gave the Horcrux to Kreacher, told him to destroy it and we then killed by the inferi. Nobody knew he had betrayed Voldemort until Harry, Ron and Hermione discovered he was R.A.B.
