Are there any Air Benders who don't identify with the Nomads?

I barely remember ATLA, and have heard a little of Korra. I know that at some point in Korra, Non-Benders begin to begin 'popping up' as Air Benders. Using content from these two shows, are there any Air Benders who don't identify with the Nomads, and are completely disassociated from the Nomads?

When Air Benders started resurfacing, did only non-benders who encompassed the Nomad way of life get Air Bending?
