I chronicles 2:13-16 gives a very detailed list. (Including 2 Sisters!!)

13 Jesse begot Eliab his firstborn, Abinadab the second, Shimea the third, 14 Nethanel the fourth, Raddai the fifth, 15 Ozem the sixth, and David the seventh.

16 Now their sisters were Zeruiah and Abigail. And the sons of Zeruiah were Abishai, Joab, and Asahel-three.
