"Go a-googling"--I like it. Could be made into a song...
Be that as it may--I was surprised to see that a cadger was a packman. Weren't packmen people who went about with a horse or a mule which was laden, with things to be sold, or perhaps simply transported? I suppose there were some who picked things up as they went, but that has not been my understanding of the primary definition of packman.
I'm not sure if I've ever heard the word cadger. As far as I know, the verb cadge generally means to ask to be given something, with the connotation that the recipient should then owe the giver a favor, because at the moment, the recipient cannot reciprocate and both parties know it.
I'm hoping one of our language gurus can either correct my understanding of these two words, or tell me how they came to diverge in meaning.

Interesting--one time before, I accidentally typed a different color word after the /, and the post came out looking like I wanted it to. This time, I had typed /i, and the bolding did not end.
