Hmm, I don't know of any Knibbs travellers but I have a couple of ancestors who were half-blooded with non-Romani fathers and non-Romani surnames but they lived as gypsies as was their mother's blood.
But just because I don't know of the name doesn't mean he wasn't a traveller, I am not an authority.

Is there any other information you can give us such as first name, age, location? Often being able to see him in context on a census can help.
I know what you mean about Ag Labs, I am beginning to form an irrational hatred for farm workers.
