Ripley - when we got him as a kitten my husband wanted to name him Sam but I wanted something more original. I thought and thought until Ripley from the Alien movies came to mind and I thought that fit a cat well because he can really rip you one with his claws. My mom always called him Ripsnorter which cracks me up.

Jazz - I found the name on an internet list of cat names. It made our top five list and then we finally narrowed it down to that because we both really love jazz music. I really wanted to call her Boo but my husband hated it so now that is her nickname from me, Boo Kitty.
Her name at the shelter was Chrissy.

Scout - it was on that internet list too and I narrowed it down to either Scout, Rio or Pico. I really wanted an O ending name but when hubby heard Scout he really liked it so there ya go. I also wanted to call her Roo from Winnie the Pooh but hubby hated that too so her nickname is ScoutyRoo.
Her name at the shelter was Goldie.
