Hi jenny,
it's Ted Whiteaker here. Been doing some research on Carl for a Facebook site called "Darwin and The Top End" and have recently posted some pics from the NT Library site and other places - you might like to check it out. I can't help you with your ancestry, but I've been thinking of you and bugger me - there you are! Like a time capsule from the past (your message is dated 2009!)..... let's see if you get this little whisper through cyber space....
cheers!
