He and Dawn were also professional quality amateur photographers and enjoyed doing nature shoots together. He was preceded in death by his mother, father, and first wife.  He is survived by his wife, his children Zack (Maggie) and Andy (Ronda) Martin, his step children Jason (Lisa) Knepp, Sarah (Billy) O'Hara, and Steven (Shayne Marvin) Norton, and his twelve grandchildren Ethan (Cassie) Knepp, Bryce Knepp, Jenna Knepp, Collin O'Hara, Olivia Haase, Blake O'Hara, Anna Martin, Amelia Martin, Trace Norton, Emmalyn Martin, Tayrock Norton, and AJ Martin.
